My son has paid little on his student loans since graduating 5 years ago. Interest is accruing and I occassionally get threatening letters from Sallie Mae when he forgets to pay or defer the loan. He will be coming into some prize money that can pay of a good portion of the loan but plans to use the money to travel and reward friends. Can I have a lien put on the prize money so that it must be used to pay off the loan? Any other options? My son lives in California, so, if available to me as an option, do I need to use legal services there if I want to litigate or place a lien?
