I did consult with my attorney. They said I can write up an agreement for a temporary visit with the grandparents due to the situation. It will include who is responsible for DS during the visit, when and where pickups/drop-offs will be, what states he is allowed to go to. She will sign it and I will sign it. It will also include her driver's license #, make, model and tag # for her car.
After having full physical custody of DS 24/7 for the past 19 months, a weekend by myself is so tempting. I do think my sister-in-law will be responsible and bring him home. Plus, I don't want to make ANY waves to have the judge look unfavorably on me - like I am withholding DS from stbx's family. If I do what's right for the family, and trust that my sister-in-law will do the same, everything should work out just fine. Am I just trying to justify this?
The suggestion to take him down there myself for the visit is a good one. However, everyone knows a 20 minute visit isn't the same as staying over. Having meals together. Hanging out. I personally won't hang out there so DS would have to do it without me. Plus, I can't imagine myself having to drive 5 hrs home after the 20 minute visit with shot nerves. Also, I already have a commitment for Friday that I really can't back out of. I'm involved in running a singles picnic for 150 people at my church. I can't stiff them for the whims of my stbx's family.
I am going to trust my sister-in-law on this one. Write the temp visitation letter. And put the situation in God's hands.
I did take all your responses to heart. Thanks for caring enough to answer.
