How do you address your future in-laws? When did you start using their first names?

I've always called my FFIL by his first name, he's actually my DH's step father, so even he calls him by his first name.

I call my FH mother (Mom) and he calls mine the same or MNL for mother in law it's their joke because she calls him her SNL for son in law.

I never once have called them by their last name, neither side are very formal with names, me and my FH have a daughter together so it was always Grandma and Grandpa, but after we got engaged i started to just call them Mom and Dad. they really like being called mom and dad so i just stick with that.

I call my FIL's mom and dad even though I still have my mom and dad

I avoided calling them anything for a long time, but now I use first names. DH and I have been together since we were 16 so I've known them forever, but it would have been weird to call them by first names initially. I think I started calling them by their first names sometime in college.

I met FH'S parents on our first date. We went to a Twins game with them. I have always called them by their first names.

I call them mom and dad. I've known them my whole life and while they can be a pain sometimes, they're the best.

Whenever I asked they said they preferred "Mom and Dad" over their first names. Doesn't bother me because we really do have a good relationship, for which I'm very thankful for!

I was close to my husbands family long before we got together and married. His sister has been my best friend for over 20 years and I called his parents mom & dad for almost as long.

I've always called them by their first names. Always.

Hahaha exact same as Orchids.

Always by their first names....now, it's been more "mom and dad" since it's easier when all the family is around.

Initially I avoided calling them anything at all. But both of his parents have referred to me as "daughter" since the very beginning. So I call them mom and dad.

I just know in our culture, you NEVER call an elder by their first name until they tell you to, and even then don't do it in front of your own parents. Even my dad still calls my grandmother Mrs. first name.

I for the most part have avoided calling them anything. For FH mother I use diversions like "Hey Lady" & "Mama Last-name"

FH and I both use first names when talking to our respective in laws... I often call his mom 'Mama Mi' which is what our son calls her. We're very close!

I've avoided calling them anything so far. He isn't super close to them and in the almost 6 years we've been together I've only met them a handful of times. He calls my parents by their first names though.

I have always used their first names.

I normally call them by their first name. I have for a couple years now. I have noticed though I call them "Grammy and Pop Pop" a lot since that's what our son calls them.

By their first names, but I call his grandpa, grandpa.

Unfortunately this is a problem I haven't dealt with.... My Mil passed away before I met FH, and my FFIL passed away shortly after I met him so I never really called him anything. My FH just refers to my mom as mom my step-dad, dad and step-mom by first name. We have been together for 12 years and this is what he is comfortable with.
