I posted this in your thread, but wanted to be sure you saw it.

save a trip and contact your original lessee. They will probally be able to tell you, or call the landman that leased you.

Even if the lease is assigned, The assignee or sublessor is bound by any notice or demand sent to the original lessee, UNLESS the lessor has been given written notice of the assignment or sublease AND the assignment or sublease has been recorded.

IF the above two conditions of notice and an recording have taken place, then all subsequnt notices must be made on the assignee.

Wooley Bully,

I looked up Bossier for you. I did not find anything for MAC Resources or M.A.C. Resources.

Sorry that is the only Parish I subscribe to. The Clerk's office may check to see who it was assingned to for you if you call.
