The question I have is,I have a son whom recently married a young lady March 26 2009 and since then she has committed adultery.There is an unborn child and I am not for certain it is truly his and if it is I would like to know how to obtain custody of the child once it is born or what is my rights as a grandmother.My son plans on supporting the child and will have full military benefits.The young lady does not have any financial support for her self let alone have any for the baby once it is born,she is very unstable as well as undecive.I would like to know where I stand as a grandmother.

It's far too soon to have grandparent rights.
I see this is a speeding train about to derail. You need to stay out of your son's marriage, period. This is 100% none of your business. It's chilling to read 'I am not for certain it is truly his.' You have no right to even be making that statement. That is for your SON to be saying, and he has spoken: he will be father to the child. You talk about his WIFE as a young lady with no financial support for herself and the baby, which is a flat out lie - she's his WIFE and does have support - HIS and his benefits. Back off, or you will make this far, far worse than you think it is now. You may find yourself with a son who will have nothing to do with you and a daughter in law who will leave, with the child, faster than you can say what did I do?

One very basic and compelling reason to stay out of their marriage is that you don't know ANYTHING, really. You weren't there watching her 'commit adultery' with a man. You don't know if your son has had an affair or had a child with another woman, even though you may think you know, or if he said something or did something, who knows what.

I recently answered an ad for a free kitten. The house was full of cats and smelled. A crazy cat lady? She has a full time job and didn't seem crazy at all. She gave me an adorable kitten and warned me it had fleas. An irresponsible cat lady?
Turns out all the cats were her husband's comfort and companions while he was home dying of cancer. He had just died, and she was finding homes for them. A shelter was coming the next day to get many of them.

You NEVER know the whole story, do you?

Normally, I might object to Joy's posts here because this is the law forum and answers here must conform to existing statute. But she did tell you it was too early for grandparent's rights. Besides with I so totally agree with her.

This is your son's problem and you NEED to stay out of it. Legally you don't stand a chance of getting custody of this child.

The mother or the father can fight for custody, not you.

Next if the child is not even your sons child, you would not even have grandparents rights ( and that only allows you to visit

I also agree, this is what you want, what does the father and mother of the child want
