No they are not. However, this is true if you have been married for 7 months or 7 years. The general rule is that money received has the result of an inheritance or gift is considered to be separate property. And only marital property can be distributed to the other spouse in a divorce. This is true whether you live in a community property state or an equitable distribution state (like FL). Therefore, as long as the $20,000 was an inheritance given to you and only you (i.e. not to you and your spouse), it is not marital property subject to division in a divorce.
