The answer is maybe if you contributed funds to it.Arizona does not require the division of marital property in divorce to be exactly equal, but it must be fair and will usually be approximately equal.
There is a strong presumption under Arizona law that all assets and debts a couple accumulates during marriage are community (marital) property. Property one spouse owned alone before the marriage, or acquired by gift or inheritance during the marriage, is that spouse’s separate property, as long as that spouse can prove the claim with financial records or other documents.
Spouses may change an asset that was originally separate property into community property, or vice versa. For example, if a spouse who was the sole owner of the family home before the marriage changes the title to community property, a court would consider this evidence that the owner intended to make a "gift" of the home to the marital community.
Sometimes a spouse changes a separate asset into a community asset without meaning to by combining—or "commingling"—separate property with marital property. A premarital bank account belonging to one spouse can become marital property if the other spouse makes deposits to it; a house owned by one spouse alone can become marital property (either in whole or in part) if both spouses pay the mortgage and other expenses. Many types of assets can be partially community and partially separate, including retirement accounts one spouse contributed to both before and after the marriage, or a business one spouse started before marriage and continued operating after marriage.
Distinguishing community property from separate property can become very complicated, especially if one spouse owns a business or other asset to which the other contributed labor or funds during the marriage. If you have a complex property situation, you may need to consult an attorney for advice. Spouses who can’t decide what belongs to whom will have to let a court decide whether commingled property was a gift to the marriage or whether the original owner should be reimbursed in whole or in part.
