I think it depends what state you are in and how good the forms generally are from a legal stand point.

We sold a house FSBO and just used an attorney. It was easy peasy and only cost a few hundred dollars.

Stock forms are just that,'stock'.

Unless you have sold multiple houses and now exactly what every line in the stock form means, and what to add to the form, get an attorney.

It is all to easy to make very expensive mistakes (and even attorneys do it once in a while and get sued).

My parents did this recently on a vacation home. It was helpful that they had a cash buyer that pretty much knocked on their door and agreed to pay all closing costs.

The title company handled all the paperwork. It went very smoothly.

"The title company handled all the paperwork."

Different states use title companies in different ways.

In NH title companies handle settlements.
You can bring your attorney if you want to.

In VA settlements are conducted by attorneys.
You can still bring YOUR tourney to represent you, but they are only an observer and are not running the closing.

I would absolutely get a RE attorney for a FSBO.

I used one for my last purchase and she modified the form in at least one way that was very helpful for me in negotiations. And she wasn't very expensive (though she asked for extra because the sellers were very difficult -- I quickly obliged).

Title/Escrow companies are neutral 3rd parties, and will not give you legal advice or advocate for either side. It shouldn't cost much to get a RE attorney to draw up or review a contract.

In my opinion it is according to the situation in which you are dealing with. If you have full faith in your realtor whom you are buying a new house and she is offering less fees then you can appoint her otherwise I think you should get a real estate attorney for fsbo.
