In California, changes to spousal support, child custody, and child support can be pursued through motion work in court. Here's how it typically works:nnTemporary Spousal SupportnnTemporary spousal support can be modified at any time upon demonstrating a change of circumstances. This change could involve alterations in income or living situations, among other factors. A motion is filed, arguments are presented in court, and temporary spousal support can be adjusted accordingly.nnPermanent Spousal SupportnnIf spousal support is agreed upon as permanent, the court's jurisdiction may terminate upon agreement unless it's structured as indefinite long-term support. In cases where the court maintains jurisdiction, modifications may be pursued based on significant changes in circumstances, subject to court approval.nnChild SupportnnChild support orders are modifiable until they expire. Similar to spousal support, changes are based on a change of circumstances standard. This could include alterations in income, living arrangements, or other pertinent factors affecting the child's welfare. Motions are filed, and the court considers the evidence and arguments presented before making a decision.
