I cannot tell from the facts if the parties have only been separated for 3 weeks or she has just been MIA in general for 3 weeks, but if the former, unfortunately he must be separated for one full year before he can file for divorce. Other matters, whether it be children, assets, debts, alimony, etc. can be handled anytime after separation. If a separation agreement was in fact signed, then she will be held to that contract, but if you only meant they had verbally agreed on things but had not yet memorialized anything, unfortunately that will likely not be something he can prove or enforce. If they have in fact been separated for one year, a divorce can still be filed and it would need to be served through "publication" in the newspaper. He should consult with an attorney to discuss his options to best protect his rights and also discuss options about the house and debts, which are clearly the urgent matter .
