I need a paralegal from Oregon

I loaned my son who was married a onetime no interest loan from our family's savings for his divorce attorney's retainer. My son killed himself on 02/15/22 in our home, the remainder of the retainer was made out to his estate and was sent to our house (because it was his residence when he died. Now I have to file as an estate debtor being that there was not a will. I sent his wife a certified letter stating that I am needing to get my partial payment from cashing the check and that our son's estate will be responsible for the remainder. There is also text from my son's father-in-law stating that they needed all of his property back so all of the bills accrued can be paid
