When navigating the complex landscape of child custody, understanding the necessary forms is crucial. If you're seeking sole custody, this guide will walk you through the essential paperwork, ensuring you're well-equipped to navigate the legal process.

Before delving into the forms, it's vital to understand that sole custody, also known as full custody, grants one parent complete physical and legal custody of the child. The other parent may have visitation rights but no decision-making authority. Always consult with a legal professional for advice tailored to your unique situation.

Petition for Custody
The journey begins with filing a Petition for Custody (or Custody Order Modification if you're seeking a change in an existing custody arrangement). This form initiates the legal process and outlines your request for sole custody.

Here, you'll need to provide detailed information about your family, including the names and addresses of both parents, the child's birthdate and address, and a proposed parenting plan outlining your request for sole custody and a visitation schedule for the other parent.
Form C-100: Petition for Custody and Support of Minor Children

Form C-100 is the primary document used to request custody and support in California. It's crucial to fill it out accurately and completely, as any errors could delay the process or negatively impact your case.
You'll need to provide detailed information about your family, your relationship with your child, and why you believe sole custody is in your child's best interest. Be prepared to discuss your child's living arrangements, schooling, and any special needs or circumstances that may impact custody.
Form FL-300: Income and Expense Declaration

Form FL-300 is used to determine each parent's income and expenses, which can impact the custody decision and child support calculations. It's essential to provide accurate financial information, as misrepresentation can have serious legal consequences.
You'll need to list all sources of income, including wages, salaries, bonuses, and any other forms of income. Additionally, you'll detail your monthly expenses, such as housing, utilities, food, transportation, and any child-related expenses.
Temporary Orders

While your custody case is pending, you may need to request temporary orders to establish a custody arrangement and other critical issues, such as child support and spousal support.
Temporary orders provide immediate stability and ensure that both parents follow a consistent routine until a final custody decision is made. They can be requested at the same time as your initial custody petition.




















Form C-105: Request for Order
Form C-105 is used to request temporary orders for custody, visitation, child support, spousal support, and other related issues. It's essential to be specific about what you're requesting and provide a compelling reason for why the court should grant your request.
For example, you might request a temporary custody arrangement that mirrors your proposed parenting plan in your Petition for Custody. You can also request temporary child support based on your income and the other parent's income, as calculated using the state's child support guidelines.
Form C-106: Declaration for Request for Order
Form C-106 is a sworn statement supporting your Request for Order (Form C-105). It provides detailed information about your family, the requested orders, and the reasons why the court should grant your requests.
Here, you'll need to explain why sole custody is in your child's best interest and provide any evidence supporting your claims. This could include letters from teachers, therapists, or other individuals who can attest to your child's well-being and the other parent's unsuitability for custody.
Navigating the legal system can be daunting, but understanding the necessary forms is the first step in seeking sole custody. Always consult with a legal professional to ensure you're completing these forms accurately and that your rights are protected throughout the process. By staying informed and proactive, you're taking a crucial step in securing your child's future.
