I believe the first step would be to ask the Landman to provide you with a copy of whatever lease that they are asking for you to ratify. Before signing anything then have your O&G lawyer look over that document as well as any ratification documents that they are requesting so you can than have the proper information at hand and know exactly what you are approving/ratifiying and whether it is in your best interests to do so at all.
We know, J.R., that if those were your own minerals there is no way in hell a Ewing sould sign those ratification documents without first reviewing a copy of what (most likely unfavorable) terms are grandfathered into that document being signed. LOL.
If, after seeing the lease you (and/or your O&G lawyer) are comfortable with the terms that you are approving then by all means go ahead and ratify the document and start recieving royalty.
If the terms stink, however, then have a discussion with your O&G lawyer as to what alternative options you might have. The fact that they are looking to recieve your ratification does offer you some recourse.
Here's another discussion thread with some information that is useful to this topic:
