A California family law attorney handles the legal issues that arise when a family relationship changes, including child support, spousal support, domestic violence restraining orders, parentage, prenuptial agreements, and the modification and enforcement of existing orders. Many of these matters arise within a divorce or custody case, but each can also arise on its own and follows its own statutes and deadlines. Wade Litigation, led by Amiel Wade and recognized among the Top Ten California Family Law Attorneys, represents clients in all of these matters across California and offers a case evaluation to review your situation as a whole.
This page focuses on the support, protection, and agreement questions that Californians search for most: how child support is calculated, how spousal support works, how to get a restraining order, and how a prenuptial agreement is enforced. Our divorce page covers divorce procedure and property division, and our custody page covers parenting decisions, so each page answers its own questions without repeating the others.
How Child Support Is Calculated in California
Child support is the highest-volume family law topic in California by a wide margin, with searches for the topic and for calculators far outnumbering any other family law question. A statewide guideline in Family Code section 4055 sets the amount. The formula considers each parent’s net monthly disposable income, the percentage of time each parent has the children, the number of children, and a multiplier that adjusts for income level. Because these inputs drive the amount, the most common source of disputes is not the formula but the inputs: what counts as income, whether a parent is voluntarily underemployed, and how much time each parent actually has the child.
Figure 1: What Californians search about support and orders (U.S. monthly searches, Ahrefs, 2026).
Income for support purposes is broader than a paycheck. It can include bonuses, commissions, self-employment profits, rental income, and, in some cases, investment income, and a court can impute income to a parent who is capable of earning more but chooses not to. Childcare, uninsured health costs, and educational expenses are handled separately. Support generally continues until a child turns 18, or until 19 if the child is still a full-time high school student and unmarried, under Family Code section 3901.
Guideline calculators are widely used and useful for estimates, but they depend on accurate inputs and do not capture every adjustment. Parents can request a modification when circumstances change, and our guide to modifying a family court order in California explains the showing a court expects. High earners face particular issues, which we address in our article on child support for high-income earners in California.
How Spousal Support Works in California
Spousal support, often called alimony, is decided differently from child support because there is no single formula for long-term support. Family Code section 4320 lists the factors a court must weigh, including the marital standard of living, each spouse’s earning capacity and ability to pay, the age and health of both spouses, the duration of the marriage, and the supported spouse’s ability to become self-supporting. Temporary support during the case is often set using a county guideline calculator, and counties publish their own versions, so the same facts can produce somewhat different temporary figures in different courts.
Duration depends largely on the length of the marriage. For marriages of less than ten years, section 4320(l) states a general goal that the supported spouse become self-supporting within a period of about half the length of the marriage. For marriages of ten years or more, the law treats the marriage as one of long duration and the court generally retains jurisdiction to modify or terminate support later, rather than setting a firm end date.
Figure 2: Marriage length versus the guideline goal period for spousal support when a marriage is under ten years.
Support can be modified when circumstances change materially, such as a job loss, a retirement, or a substantial change in income, which we explain in our article on modifying spousal support after an income change. Our overview of alimony in California and how it is calculated covers the statutory factors in more detail. Spousal support is not taxable to the recipient or deductible by the payor for federal purposes under current law for orders made after 2018, but California treats it differently for state income tax purposes, so tax advice is wise.
How to Get a Restraining Order in California
A domestic violence restraining order protects a person from abuse by a spouse, former spouse, dating or cohabiting partner, or close family member under the Domestic Violence Prevention Act, Family Code section 6200 and following. The process starts with a request on Judicial Council forms describing the abuse. A judge can issue a temporary restraining order, often the same day, without the other person present. The court then sets a hearing, generally within 21 days under Family Code section 242, or up to 25 days if extended, at which both sides may present evidence. After the hearing, the court may issue an order that lasts up to five years under section 6345 and can be renewed.
Figure 3: How a domestic violence restraining order moves forward, in days after filing.
A restraining order can do more than keep a person away. It can address temporary custody and visitation, exclusive use of a shared home, support payments, and the surrender of firearms. Because an order has serious consequences for the person restrained, including effects on custody and employment, those who receive a request must respond carefully and on time. Wade Litigation represents both people seeking protection and people responding to a request, and treats evidence, credibility, and compliance as central to either side.
Establishing Parentage
Legal parentage underpins custody, visitation, and support for unmarried parents. You can establish it through a voluntary declaration of parentage signed at the hospital or later, by a judgment, or through the presumptions in the Uniform Parentage Act, Family Code section 7600 and following. Parentage can also be contested, and a signed declaration can become difficult to challenge after a short period, so acting promptly matters. Our guide to establishing parentage in California explains each route and the rights it creates.
Families formed through assisted reproduction, surrogacy, or adoption raise additional questions, as do same-sex couples whose children were born before certain protections were clarified. In each case, the safest step is a court judgment of parentage, which is recognized across states and cannot easily be collaterally attacked later.
Prenuptial and Postnuptial Agreements in California
A prenuptial agreement lets a couple decide in advance how property and support will be handled if the marriage ends, and a postnuptial agreement does the same during the marriage. California enforces these agreements under the Uniform Premarital Agreement Act, Family Code section 1610 and following, but a party can challenge an agreement that was not voluntary or that was unconscionable and not accompanied by adequate disclosure. Since 2002, an agreement is presumed involuntary unless the party seeking enforcement shows that the other party had independent counsel or knowingly waived it and had seven calendar days to review the final agreement before signing, under section 1615.
Provisions waiving spousal support receive extra scrutiny and are unenforceable if the waiving spouse did not have independent counsel when the agreement was signed or if enforcement would be unconscionable when applied. Child-related terms cannot limit a child’s right to support. A well-drafted agreement lists assets and debts, defines separate and community property, addresses business and retirement interests, and provides for periodic review.

Modifying and Enforcing Family Court Orders
Family court orders are not permanent. Support and custody orders can be modified on a showing of changed circumstances, while property division judgments are generally final. A parent who does not receive support can seek enforcement through the county’s local child support agency or through the court, using tools such as wage assignments, tax intercepts, license suspensions, and contempt. A party who stops paying cannot unilaterally reduce support; the order stays in force until the court changes it, and unpaid support accrues with interest. Document income changes and file promptly for modification to protect against arrears.
Family Law and Immigration, Military, and Out-of-State Complications
Some family cases cross borders that the statutes treat differently. A spouse who has moved out of state can complicate which court has jurisdiction over custody under the Uniform Child Custody Jurisdiction and Enforcement Act and over support under the Uniform Interstate Family Support Act. Military service affects scheduling protections and how retirement pay is divided. Immigration status can influence what a spouse wants to resolve and how quickly. Identifying these facts at the outset helps keep a case from being filed in the wrong place or settled on terms that don’t work across borders.
Attorney Fees and Costs in Family Cases
Family Code sections 2030 and 271 let a court order one party to pay part of the other’s attorney fees based on need and ability to pay, and to sanction conduct that frustrates settlement or increases cost. These provisions are meant to equalize access to counsel between a spouse who controls the money and one who does not. A request requires a declaration of income and expenses and is decided at the court’s discretion, so early and complete financial documentation matters.
How Family Law Courts Differ Across California
The statutes apply statewide, but where hearings occur, how temporary support is calculated, and how restraining order matters are routed differ by county. The table summarizes verified information for the regions where Wade Litigation practices.

What This Means for Your Case
Family law issues rarely arrive alone, and a decision in one area shapes the others. An agreement on parenting time changes the child support formula, a property settlement can change who needs spousal support, and a restraining order can shape custody. Reviewing the full picture at the start, rather than addressing each issue as it appears, keeps a strategy consistent and prevents agreements that look sensible in isolation from causing problems later.
Objections We Commonly Address
Clients sometimes delay getting legal advice because they hope to settle informally or worry that hiring a lawyer will escalate conflict. Clear legal guidance early usually reduces conflict by giving both parties a realistic framework for negotiation, and informal arrangements about support or parenting are difficult to enforce when they are not part of a court order.
What Happens When You Call
When you call Wade Litigation, the intake team asks which family law issues you are facing, whether any orders exist, and what deadlines are running. During the case evaluation, an attorney reviews your situation as a whole, explains how the issues connect, and recommends next steps.
