How to File for Divorce in California: A Step-by-Step Guide for Carlsbad Residents

If you live in Carlsbad and want a divorce, one spouse must meet California's residency rule. A petition is then filed with the San Diego County Superior Court and served on the other spouse. Both spouses exchange sworn financial disclosures and settle or go to hearings, and no judgment of dissolution is final for the purpose of terminating the marriage until six months have expired from service or the respondent's appearance, whichever occurs first.

Most people facing this process arrive at it carrying something heavy. There may be a conversation at the kitchen table that cannot be taken back, a spouse who has already moved out, or children asking questions with no good answers yet. Under all of that sits a practical worry: what actually happens first, what comes after it, and how long it lasts. This guide walks through the filing process in order, the way it runs for a case started in Carlsbad and heard at the North County courthouse. It covers the prerequisites, five steps, the points where cases can get more complicated, and the timing rules.

The short version is five steps, with a six-month minimum before a dissolution judgment is final. The site's California divorce process timeline covers the calendar in more depth.

Before You Start: Residency, Grounds, and Decisions to Make

Residency comes first. Under Family Code section 2320, a judgment of dissolution generally cannot be entered unless one spouse has lived in California for six months and in the county where the case is filed for three months immediately before the petition is filed. For a Carlsbad case, that county is San Diego County. Only one spouse has to qualify. A narrow exception exists for certain same-sex marriages entered in California; it is outside the scope of this guide.

Grounds. Family Code section 2310 says dissolution of marriage or legal separation "may be based on either of the following grounds, which shall be pleaded generally": irreconcilable differences, which have caused the irremediable breakdown of the marriage, or permanent legal incapacity to make decisions. Neither ground is based on one spouse's fault. Section 2311 describes irreconcilable differences as "those grounds which are determined by the court to be substantial reasons for not continuing the marriage and which make it appear that the marriage should be dissolved."

Dissolution and legal separation are different requests. Family Code section 2330 requires the petition to say whether it asks for dissolution of marriage or legal separation.

A few decisions shape the whole path:

• Contested or uncontested. A case is uncontested when the spouses agree, or can come to agree, on every issue. It is contested when one or more issues need a judge to decide. The site's page on uncontested divorce in Carlsbad explains that path in detail.
• Children. Custody, visitation, and child support add their own requirements, including mandatory mediation when custody is disputed.
• Property. A home, retirement accounts, or a business all add valuation and division work.

Summary dissolution is a separate, simplified procedure. Under Family Code section 2400, it is available only when every condition is met. These include, among other things, a marriage of no more than five years as of separation, no children of the relationship born before or during the marriage or adopted during it and no known pregnancy, no interest in real property other than a qualifying residential lease, limits on debts and on community and separate property, a written property agreement, a waiver of spousal support, and a waiver of the rights to appeal and to move for a new trial. The debt and asset limits are set by statute and adjusted periodically under section 2400(b), so any fixed figure quickly goes out of date. Summary dissolution is started by filing a joint petition for summary dissolution (section 2401(a)), and under section 2403, when six months have expired from the date of the filing of that joint petition, the court "shall, unless a revocation has been filed pursuant to Section 2402, enter the judgment dissolving the marriage." Summary dissolution is a different procedure from a joint petition under section 2330.

The courthouse. Carlsbad cases are filed in San Diego County. Family law matters from Carlsbad are generally heard at the Superior Court of California, County of San Diego, North County Regional Center, 325 South Melrose Drive, Vista, CA 92081. The court describes that courthouse as serving most of northern San Diego County.

Step 1: Prepare and File the Petition

Filing the petition opens the case. Family Code section 2330 says a dissolution proceeding is "commenced by filing a petition," or a joint petition, titled In re the marriage of the two spouses. The spouse who files is called the petitioner. The other spouse is the respondent.

The petition states what the petitioner is asking the court to order. Section 2330(b) requires it to include, as nearly as can be determined:

• the date of marriage
• the date of separation
• the number of years from marriage to separation
• the number of children of the marriage, or a statement that there are none
• the age and birth date of each minor child

When both spouses file a joint petition, section 2330(c) requires a list of the issues they intend to resolve by agreement. That list can include custody, child support, spousal support, separate and community property, restoration of a former name, and attorney's fees. If any issue is not going to be resolved by agreement, the standard petition is used instead.

Joint petitions. Section 2342.5, operative January 1, 2026, covers a joint petition for dissolution of marriage or legal separation filed with a joint summons under sections 2330 and 2331. Under section 2331(b), "the joint petition shall be deemed to be served on both parties upon the filing of the joint petition with the court and both parties shall be determined to have appeared in the matter." A joint summons includes the temporary restraining order required by section 2040 (section 2342.5(a)(2)). Before judgment on the joint petition is entered, a petitioner may file an amended petition or the respondent an amended response without leave of court; if either is filed, the joint petition is deemed revoked and the case proceeds as a petition under section 2330, with the joint petition's filing date treated as the filing date for deadlines such as section 2339 (section 2342.5(b)(1) and (3)).

Where and how. Family law cases from Carlsbad are generally heard at the North County Regional Center in Vista. The Judicial Council forms and step-by-step instructions are available through the California Courts Self-Help Guide. Local filing information and family law self-help resources are on the Superior Court of San Diego County website. Filing fees and fee-waiver information are published by the court and are not covered here.

What comes next: the papers have to reach the other spouse.

Step 2: Serve the Other Spouse

Service is the formal delivery of the summons and petition to the respondent, completed and documented according to California's service rules. Several of the deadlines discussed below are measured from the date of service or from the response.

The summons. Under Family Code section 2040(a), the summons contains a temporary restraining order. It restrains both parties from removing the minor children from the state, or applying for a new or replacement passport for them, without the other party's prior written consent or a court order. It restrains both parties from transferring, encumbering, hypothecating, concealing, or in any way disposing of any property, whether community, quasi-community, or separate, without the other party's written consent or a court order, except in the usual course of business or for the necessities of life; each party must also notify the other of proposed extraordinary expenditures at least five business days before incurring them and account to the court for them. It restrains both parties from cashing, borrowing against, canceling, transferring, disposing of, or changing the beneficiaries of insurance or other coverage held for the benefit of the parties and their children for whom support may be ordered. And it restrains both parties from creating or modifying a nonprobate transfer in a manner that affects the disposition of property subject to the transfer, without written consent or a court order. Section 2040(b) lists things the order does not restrain, such as creating, modifying, or revoking a will. Under section 233(a), the order is in effect upon the filing of the petition and issuance of the summons and upon personal service on the respondent (or waiver and acceptance of service), and it remains in effect until final judgment is entered, the petition is dismissed, or the court orders otherwise.

Service starts the clock. Under Family Code section 2339(a), subject to subdivision (b) and sections 2340 to 2344, no judgment of dissolution is final for the purpose of terminating the marriage until six months have expired from the date of service of the summons and petition, or the date the respondent appears, whichever occurs first. For a standard petition, the date of filing does not start this period. A petition filed in March but served in May starts its six months in May, unless the respondent appeared in the case earlier.

Service on a spouse who cannot be found. Under Code of Civil Procedure section 415.50(a), a summons may be served by publication if, upon affidavit, it appears to the satisfaction of the court that the party to be served cannot with reasonable diligence be served in another manner specified in that article and one of the further conditions in the statute is met. The court orders the summons published in a named newspaper most likely to give actual notice to the party to be served (section 415.50(b)). Family Code section 210 applies the rules of practice and procedure for civil actions generally to proceedings under the Family Code, except where another statute or Judicial Council rule provides otherwise. Family Code section 2104(f) addresses one effect of service by publication or posting under court order: it sets a different deadline for the petitioner's preliminary declaration of disclosure (see Step 3).

What comes next: the money conversation begins, on paper and under oath.

Step 3: Exchange Financial Disclosures

Under Family Code section 2104(a), each spouse must serve the other with a preliminary declaration of disclosure, signed under penalty of perjury on a Judicial Council form. A court order for good cause can change this, as can a few narrow exceptions written into the statute.

Time to respond. Under Family Code section 2020, a responsive pleading, if any, "shall be filed and a copy served on the petitioner within 30 days of the date of the service on the respondent of a copy of the petition and summons."

The deadline is fixed. Section 2104(f) says the petitioner serves the preliminary declaration with the petition or within 60 days of filing it. The respondent serves theirs with the response or within 60 days of filing it. If the petitioner served the summons and petition by publication or posting under court order and the respondent files a response before a default judgment is entered, the petitioner has 30 days from the response being filed. The spouses can extend these periods by written agreement, or the court can extend them by order.

What it contains. Section 2104(c) requires the declaration to identify all assets in which the spouse has or may have an interest and all debts for which the spouse is or may be liable. This includes community, quasi-community, and separate property, along with the spouse's ownership percentage where property is shared. It must include all tax returns filed in the prior two years. Under section 2104(e), each party also provides a completed income and expense declaration along with it, unless one has already been provided and is current and valid. The site's financial documents checklist lists what typically gets gathered.

What gets filed. The declaration itself is not filed with the court unless a court orders it. Only the proof of service is filed (section 2104(b)). A spouse can amend the declaration without permission, as long as proof of service of the amendment is filed (section 2104(d)).

Why accuracy matters. Section 2104(a) states that perjury on the preliminary declaration may be grounds for setting aside the judgment, in whole or in part, in addition to other civil or criminal remedies.

Valuation is not frozen at separation. Family Code section 2552 directs the court to value assets and debts as near as practicable to the time of trial. On 30 days' notice and for good cause, the court may use a date after separation and before trial.

What comes next: with the finances on the table, the case moves toward agreement or toward hearings.

Step 4: Reach Agreement or Prepare for Hearings

This is the step where cases divide into two paths. For many readers it is also the step that carries the most worry, because it is where decisions about children and the home actually get made.

The uncontested path. The spouses may resolve issues by agreement. Under Family Code section 2550, the court divides the community estate equally except upon the written agreement of the parties or an oral stipulation of the parties in open court. The site's page on divorce mediation in Carlsbad describes one way spouses reach that agreement.

The contested path. Issues the spouses cannot resolve are decided by the court. While the case is pending, the court can also make temporary orders. Under Family Code section 3600, during the pendency of a proceeding for dissolution of marriage, the court may order either spouse to pay any amount necessary for the support of the other spouse, consistent with the requirements of subdivisions (i) and (m) of section 4320 and section 4325, or order either or both parents to pay any amount necessary for the support of a child. Under section 3022, the court may, during the pendency of a proceeding or at any time thereafter, make an order for the custody of a child during minority that seems necessary or proper.

Custody mediation is required when custody is contested. Under Family Code section 3170(a), when a request for a custody or visitation order shows those issues are contested, the court must set them for mediation. In San Diego County, that mediation is child custody recommending counseling through the court's Family Court Services (Family Code sections 3170 and 3183). Under section 3183(a), the mediator, called a child custody recommending counselor, may submit a recommendation to the court on custody or visitation, consistent with local court rules. The counselor must first give it in writing to the parties and their attorneys before the hearing. Family Court Services, which calls this person the Family Court Counselor, explains that if no agreement is reached, the counselor makes a recommendation to the court and the hearing goes forward. The judge decides. Under section 3183(b) and (c), the counselor may also recommend an investigation, other services, or restraining orders to protect the child.

Domestic violence cases follow their own protocol. Section 3170(b) requires Family Court Services to handle them under a separate written protocol approved by the Judicial Council.

How property is divided. Under Family Code section 2550, except upon the written agreement of the parties or on oral stipulation of the parties in open court, or as otherwise provided in that division, the court divides the community estate equally. The community estate "includes both community property and quasi-community property" (Family Code section 63). Except as otherwise provided by statute, property acquired by a married person during the marriage while domiciled in California is community property (section 760). Family Code section 2640 addresses one specific situation: a spouse who traces separate-property money into community property, such as a down payment or principal paydown, is generally reimbursed without interest, up to the property's net value, unless that right was waived in writing. The reverse situation is a separate rule. Section 2640 does not address the opposite situation, community money paying down the loan on one spouse's separate-property home. The site's page on complex financial divorce goes further into both.

Businesses. A business's value can include goodwill. That value is decided on the evidence, often with expert testimony.

What comes next: the calendar, and the judgment.

Step 5: The Six-Month Waiting Period and Final Judgment

Six months is a floor, not a target. Section 2339(a) sets the minimum: no judgment can end the marriage until six months have run from service of the summons and petition or the respondent's appearance, whichever is first. Section 2339(b) allows the court to extend that period for good cause shown. Section 2339(a) is subject to sections 2340 to 2344, which this guide does not cover.

The case keeps moving during the wait. The preliminary disclosure deadlines in section 2104(f) are measured in days from filing or from the response, not from the end of the six months.

How it concludes. Under section 2339(a), no judgment of dissolution is final for the purpose of terminating the marriage until six months have expired from service or the respondent's appearance, whichever occurs first, subject to the court's power to extend that period and to sections 2340 to 2344. Under section 2340, a judgment of dissolution must specify the date on which it becomes finally effective for the purpose of terminating the marriage.

A former name. Section 2330(c) lists restoration of a former name among the issues spouses filing a joint petition may intend to resolve by agreement. In a proceeding for dissolution of marriage, but not in a proceeding for legal separation, the court, upon the request of a party, "shall restore the birth name or former name of that party, regardless of whether a request for restoration of the name was included in the petition" (section 2080).

When the Process Gets More Complicated

Some readers will recognize their own situation in one of the subsections below. That recognition is useful because it explains why a case may run longer than six months. It does not predict how a case will end.

Contested custody

Mandatory mediation through Family Court Services adds a stage before any custody hearing. If no agreement is reached, the Family Court Counselor makes a recommendation and the court holds a hearing. Under section 3183(b), the counselor may also recommend an investigation.

Complex or high-value property

Because section 2552 ties value to a date near trial, values may need updating as the case goes on.

Business valuation

Goodwill and other intangible value are decided on the evidence, which often involves experts.

Domestic violence

Family Court Services handles these cases under the Judicial Council protocol required by section 3170(b). Section 3183(c) also lets the custody counselor recommend restraining orders to protect a child. During the pendency of the proceeding, section 2045 also allows the court, on application of a party, to issue ex parte an order restraining the transfer or concealment of property, a protective order as defined in section 6218, and any other order as provided in the Domestic Violence Prevention Act's article on ex parte orders (section 6320 and following).

Default cases

In a default case, section 2336(a) provides that no judgment of dissolution may be granted upon the default of one of the parties alone; the court must require proof of the grounds alleged, and the proof, if not taken before the court, is by affidavit. Section 2104(f) addresses one default situation: when the petitioner served by publication or posting under court order and the respondent files a response before a default judgment is entered, the petitioner serves the preliminary declaration of disclosure within 30 days of the response being filed.

Typical Timeline: What to Expect from Filing to Judgment

Delays can come from sources such as:

• incomplete or late disclosures
• difficulty locating and serving the respondent
• contested hearings and custody recommending counseling
• court scheduling
• the complexity of the property or custody issues

The court can lengthen the six-month period for good cause under section 2339(b).

Talking With the Firm About the Filing Process

The steps above are the same for every Carlsbad filing. How they play out is not. Residency dates, whether custody is disputed, how separate money moved through the marriage, and what a home or business is worth near trial all change the path and the pace. A consultation is a place to raise those questions. To talk with the firm about filing for divorce, call Carlsbad Family Law Advocates at (760) 840-5102 for a confidential consultation.
