How do I find an attorney that will properly draft and submit a payment agreement to the attorney that represents my ex-fiance in a civil case?

You and your former partner have ended your relationship and as part of that break-up, he has agreed to pay you the sum of xxx as settlement of claims you and he agree are owed to you. To pay you that sum of money, he is willing to sign an agreement authorizing the lawyer representing him in a pending civil lawsuit to pay over to you the sum of xxx from the net proceeds of the settlement (which amount needs to be defined as a specific dollar amount).  It is not a difficult document to draft but as a lawyer, I would want to have him and the lawyer representing him sign an acknowledgment that you have a lien on the file and that no distributions can be made to him or to any other beneficiary until the satisfaction of the obligation owed to you. This is not the type of document that you should attempt to draft yourself nor should you ask the lawyer representing him to prepare. For reasons too voluminous to go into in this response, I would also not reference any claim for emotional damages flowing from the relationship in the preamble to the agreement since same may give rise to specific concerns by the other lawyer and blow up your deal. I would keep the language simple.
