my girlfriend want to move in what do I do?

Good questions and smart to think about this ahead of time.

This varies by state. Try to read the specific laws for your state.

A few things - DO NOT say you are married to anyone.

Keep separate checking accounts.

Do not put on a tax or insurance form you are married, some people do that do get insurance benefits.

Go see a local attorney. It will be well worth the $200 fee.

Depends on what State this is in, some states after so many years you would be common partners. You bought the house before meeting you might have a leg to stand on. Don't let her move in unless you draw some documents.

If she is your g/f, she is not entitled to half your house. This only happens if you marry her and divorce. As long as the house remains in your name, she doesn't get it, nor your cars.

You need to figure out what's a fair arrangement as to her living arrangements. It's not fair if she is paying half your mortgage, yet does not get an interest in your home so it's probably better that you pay that yourself and have her pay utility and/or food bills instead. This way, it keeps the division of $$ separate but she contributes to the cost of the household.

Do NOT comingle money. You keep your bank accounts and she keeps her's.

your choices are (1) get married to avoid all of the hassle you write about, or (2) have her sign a rental agreement for a month to month basis ( NOT a yearly lease ) and she will need to viewed legally as a tenant of yours.................that is why you would not want a yearly lease, in case something happens and the relationship goes sour, a monthly agreement is easier to settle.......IF you choose to just have her move in w/o any legal paperwork, then you may face the problems you write about

prenups are for married people. The best way to handle this is to have her pay RENT each month. She NEVER!!! "helps with the mortgage". She pays RENT. And her check she gives you each month should have the word rent on the memo line.

You both should have separate bank accounts. She should pay some of the bills herself, like electric.

She will not be entitled to any of it because you owned it all prior to marriage. Once you are married, assets purchased during the marriage will be split.

If you are that worried about it, then don't let her move in. You don't exactly sound like you are in love....

You are not ready to take your affair to the next level. Be honest and tell her that.

im pretty sure that only applies if you marry her, not if shes just ur gf. it will happen if u have a kid though.
