FL-343 is a California family court attachment form used to set out detailed terms of spousal support, domestic partner support, or family support (a combined support order). When the court issues a support order—either after a hearing or as part of a judgment—FL-343 is attached to document the exact amounts, payment schedules, conditions, and enforcement provisions. This form ensures the support order is clear, legally enforceable, and consistent with California Family Code requirements.

The form specifies the exact support amount, the date payments must begin, and how often they must be paid (typically monthly). It also identifies the method of payment, such as direct payment, income withholding, or payment through the State Disbursement Unit (SDU). If arrears are owed, FL-343 allows the court to specify repayment terms, including additional monthly amounts toward past-due support. This level of detail helps avoid confusion and ensures the order can be enforced without ambiguity.

FL-343 includes space to identify whether the support is temporary (pendente lite) or permanent. Temporary support covers financial needs during the case, while permanent support is issued as part of a final judgment. The form also documents whether the support order is based on guideline calculations, a negotiated agreement, or an analysis of statutory factors such as the length of the marriage, income, earning capacity, and standard of living. For non-guideline orders, additional attachments like FL-157 or FL-343(A) may be required.

The form also outlines important conditions and legal consequences related to support. For example, it may specify that support terminates upon remarriage, death, or a specific future date. It may include provisions related to insurance, tax treatment, job search requirements, or vocational training. Courts may also include warnings about the need to report changes in income or employment. These details help both parties understand their rights and responsibilities and reduce future disputes.

In summary, FL-343 is a key attachment used to create a clear, enforceable support order for spouses, domestic partners, or families. It documents payment amounts, schedules, legal conditions, and all terms necessary for proper enforcement and compliance. By providing structure and clarity, FL-343 ensures that support obligations are accurately set out and easy for both parties—and the court—to understand and follow.
