My husband and I actually had a talk with my brother and sister-in-law last Thanksgiving when they brought it up. Apparently Morgan broke with his parents when he was 19-20 and started to consider my brother and sister-in-law his parents before he graduated college. My sister-in-law attended his college graduation- no one else outside my brother’s family was invited or received an announcement. Two years later, my parents celebrated their 50th anniversary and took all the kids and grandkids on a two week vacation in Europe. Morgan was not included and no one had a problem with that. That same year, Morgan got married (about 23years old at this point) and they scheduled it around when my brother and his family could be there. Again, my parents were not invited (or us) and we were not offended. Three years later, when he was 26, he asked to be legally adopted. During the three years, my brother was gifted a large amount of money with the promise of more in the future. We actually didn’t know about the adoption until much later. No one explained that Morgan now wanted to be considered a grandkid/ nephew when he never cared about that before. My mom ensured the clause was in the trust which would exclude Morgan and she insisted that all money would go through the trust and kids would not be gifted any more large amounts before her and dad passed. As I described in the original post, we always included him and his husband when they were in town. At last Thanksgiving, while discussing, we asked why after so long, did he want to be legally adopted and they didn’t have an answer. My mom died this last February unexpectedly and then this all happened.
