In most states the law treats the spouses’ ownership and possession of pets or companion animals following divorce like other items of personal property, such as household furnishings. If one spouse owned the pet before the marriage the pet will generally be deemed that spouse’s separate property and ownership and possession will remain with that spouse following divorce. But if the spouses acquired the pet during marriage it will be marital property (community property in community property states) and the court may award ownership of the pet to one spouse as part of the division of the marital property—sometimes using a “best interests” standard similar to the standard used in child custody determinations.

In some divorces the spouses are able to agree to a custody-sharing arrangement for a pet. And a few states (California, Illinois, and Alaska) have enacted statutes that allow family courts to treat the custody and care of children more similarly to care (support) and custody issues for children. In these states the well-being of the pet is the guiding factor for the courts in making such decisions.

In Kansas, pets are generally considered personal property in the context of divorce proceedings. If a pet was owned by one spouse prior to the marriage, it is typically regarded as that spouse's separate property, and ownership and possession will likely remain with that spouse after the divorce. However, if the pet was acquired during the marriage, it is considered marital property. Kansas courts may then decide which spouse will be awarded ownership of the pet as part of the division of marital property. Unlike the few states that have specific statutes addressing pet custody in a manner similar to child custody, Kansas does not have such laws. Therefore, the 'best interests' standard used for child custody is not formally applied to pets in Kansas. When possible, spouses are encouraged to come to an agreement regarding pet custody outside of court. If they can agree on a custody-sharing arrangement, the court will typically honor that agreement.
