Part of me feels like I should take the money because he is my father and I am due some form of reparations for his past behavior. The other part of me feels like I should refuse it on principle because he shouldn't be allowed to buy his way into being any part of my life or my wedding.
Boy does this post resonate for me!
My male parental unit cheated on my mother (I really have a hard time calling him my father, sometimes I call him my sire). One of my earliest memories is sitting/waiting in a car in a parking lot at an apartment building while he "visited" one of his girlfriends. Don't tell your mom. Ick.
My parents divorced when I was 7 or so. I literally knew no one else that had divorced parents for quite a few years. He couldn't be bothered to pay alimony or child support or hold down a job or keep a place to live or show up for his visitation. He made a lot of promises he never kept. My mom finally stopped getting my brother and I dressed and ready to go somewhere he promised to take us because she was so sick of seeing us hurt and disappointed.
He would periodically pop back into our lives, and try to play the role of our father. I was skeptical, and I hated to see my brother hurt every time he popped back out of our lives. One time he took my brother with him to another province to visit his family, got drunk, wrecked his vehicle and didn't bring my brother back. We had to scrape up the funds to fly my little brother home - he was about 12 at the time. He popped back into our lives and our home when I was about 16 or so. My mother, ever the optimist, let him move in. Suddenly I had this stranger trying to tell me when to be home from a date, etc. Didn't go well, and I pretty much made up my mind to cut contact at that time. Just iced him out. I didn't need that kind of toxicity in my life, who does? As things go, he popped back out again fairly quickly as he always did. When I was getting married, my mom was going to cash out an insurance policy to help pay for my wedding and it turned out that he had stolen it at some point! I'm not ashamed to say that I rifled through my mother's stuff to find contact info for him, and gladly made a call to the police.
Here we are 46 years later, my sire died a couple of years ago. It's really a wonder we even know about it. I really don't regret my actions. His obituary didn't even include his children (there was another after my brother and I with his AP who he did marry and divorce.)
Anyway, I always felt that he owed us monetarily since he never paid support. If it had suddenly been bestowed upon us somehow, I would be in the same dilemma as you. I would want it because it's owed and not want it because really, what good is it now? I don't need it, and I sense that you don't either. You and your gf will still have the nicest day you can have, regardless. I've always said that getting married is about the marriage, not the wedding.
I had another situation in my life that reminds me of this dilemma a bit. I walked in on a home robbery many years ago. Long story short, it was a couple in my house. The male was out on parole and got sent back to prison, his girlfriend/accomplice was sentenced, in part, to make restitution to us for the window they broke to get in. I received $200 from her. And I HATED it! I felt like accepting it, even though it was to replace a window, was like taking blood money and accepting it was like telling her she was forgiven and everything was ok. Everything was not ok. It was a very traumatizing time in my life, it took me quite a while to get past it. And I took that $200 and donated it to charity. When I had it in my hands, I didn't want anything to do with it. She may never know I never took it, and I don't care. I only care about how it made me feel. And it made me feel good to refuse it.
