I very strongly believe every couple should talk to a lawyer to find out what the default state-written prenup says for their state so that you can accurately determine if a custom prenup might work better for your situation. Maybe it would, or maybe the default prenup is fine. Most people don't realize they're agreeing to a prenup one way or the other though. But you should fully understand the most important and far reaching financial legal document you'll ever sign in your entire life. You can just pay for an hour to understand the basics for your state, and if you decide to do a custom prenup then it'll be a few hundred more but then you both can feel safe knowing you're each protected. Sometimes there's some very surprising things in the default prenup, as I learned the hard way when I got divorced even though I never in a million years thought I'd ever get divorced. But shit happens sometimes.

So for things like the debt, in some states you'll become legally responsible for any future debt your spouse racks up. Spouse racks up $50k hidden credit card debt during the marriage? Well you're now legally responsible for $25k of that if you decide you can't deal with drowning in debt anymore even if none of it is in your name.

Anyways other than that, make sure you fill out the W4 for this year as if you were married because when you file your taxes next year you'll be considered married for the whole 2023 year. But also be aware that if you fill the W4 as "married" the form will by default assume only one of you is working. So you either need to allocate extra with holding (the calculator will walk you through it) or just select "single" to ensure you don't under withhold for 2023.

The biggest thing is just making sure you're on the same page about money. That you both (hopefully) prioritize saving and retirement and not spending frivolously. Because if one is a saver and one is a spender that's going to make something that should be quite easy (marriage) into something that is quite challenging.
