Your partner's name is in there, if you care about that.

You and your partner get the parking spots. You pay the bills.  If he won't tell his kids to move, you tell them to.  Or lock the garage and don't give them the code.

OR, if he's too wimpy to tell them, then you tell them that they can have one of the spots, first come first served, but you expect the other one to be left open for you.  If that fails, see above - no code to the garage.

You have bigger problems than parking. Read your own posts.

I can confidently say that everyone on this board thinks you and your DH should park in the garage and the kids should park outside. Yes, this is a big issue because you DH will not stand up for you and put his kids in their place.

Label the spots with your name and DH's names.  Then add parking to the household behavioral standards and enforce them.  No need for your ball-less DH to do it. You do it. Have any car in the parents spots towed.  They can pay the tow and storage fees to get their cars back.

When the Skids or DH cry that your kid's cars have not been towed, point out that they do not park where they have been told not to park.

Lather.............. rinse................... repeat.

Keep it simple.

This is a no brainer, OP.

The bill payers get to park in the garage. Bill payers.... that's you and your partner.

Everyone else parks where they're told to.

Why on earth do you put up with this crap?

This guy is wimpy and spineless, but you know that. You made several posts which have showed he allows his daughters to treat you and himself like dirt. 

I would have been long gone.

I'm of a slightly different opinion...

By all means, YOU should have a prime spot in the garage. However, your DH doesn't seem to care where he parks, so let him take that up with his kids. 

Unless, of course, you are paying for both cars. If that's the case, you should park your cars where you want.

I will park where I want. No if's ands or buts.  If they don't like it they can move, pay rent and park where they want. 

I think the OP's H is exactly like my ex. My ex was a nice guy, kind and caring and that's what attracted me in the first place.

But after a while, the attraction diminished, because I just couldn't believe the way he let mini wife/daughter walk all over him. He was too scared to speak up, put her in her place - in short, just parent her properly.

She would scream, yell, abuse him, manipulate, threaten suicide etc. Accuse him of being an uncaring, bad parent, not supporting her etc etc etc....To this day, she lives rent free in his large comfortable family home. He pays ALL the bills including her car, cellphone, health insurance, power, food - the list goes on. She has a 20 hour a week job, and spends all her money on herself - clothes, make up, hair extensions, drinking. She is almost 24 years old, and has no idea how to budget, or behave as an adult. She has never been taught those skills, never had to go out, live independently, make mistakes and learn from them - because DADDY takes care of everything, EVERY time. That is not how to raise your kids!

Regarding parking, haha. Of course, Princess has a parking spot in the double garage. Once I had gone over there, and parked in front of the garage on the side where she normally parked. She happened to be out. After a while she came back, and stormed into the house. We were in the kitchen however she didn't notice me at first because I was behind the pantry. She proceeded to scream at her dad - why is HER car in my way? Move it immediately - I want to park! She was swearing and cursing. Of course, he started placating her, saying oh I'll get the keys and move it, I won't be a minute bla bla bla...

I stepped out and said, what's your problem? It's not a big deal - park on the street until I leave. She gave me a filthy look, but said nothing and stormed upstairs and into her bedroom, slamming the door. 

I don't even know why I'm telling this story haha - maybe to illustrate that this was one of the reasons he is now my ex. LOL.
