Is there a statue of limitation on breach of contract?

There is a statute of limitations on breach of contract, however it can sometimes be extended.  I don't know the specific Alabama statute of limitations, but in general 20 years is way beyond the SOL for either breach of contract or fraud.  In some cases, the statute of limitations runs from when you discovered, or reasonably should have discovered, your claim, but from what you've written, it appears that you knew about your claim long ago.  It also does not seem as if your ex-boyfriend misrepresented something to you which caused you to delay filing suit.  In some states, an acknowledgement of a debt revives the limitations period, but usually that requires a written acknowledgement; I don't know whether the taped acknowledgement might be good enough in Alabama.  Also, t is possible that, in some states, the limitations period may be extended during the period when your ex was hiding.  I believe that criminal limitations periods can be extended during a time when a suspect is hiding and/or is out of state, so that even if you are beyond the limitations period for civil claims, you may be able to get your local district attorney to press charges.
