Division order incorrect interest

I received a division order but the interest was only for 20 acres not 40. Therefore, I didn’t send in the division orders. However, today I received a check for what I believe is for the 20 acre amount even when I didn’t send in the W-9 or the signed order. Should I not cash the check?? Thanks, GW

Contact the division order analyst on the DO and ask how they calculated your acres. It is possible the acreage was split and you did not know it. Also possible that they have an error. Do it as quickly as possible. I always send mine by certified mail return receipt. If you have documents that show your full 40 acres, send them a copy.
