You can create it yourself, but if you are not familiar with it you might want to find an attorney to do it. I have used land trust for over 1000 times, but I am not at liberty to give it out.
Land Trust does not need to be and can not be registered in California.
If it is an irrevocable trust, you can even get an EIN number from IRS for it...pretty cool!
Yes you can put your SCorp as Beneficiary even as a trustee of it.
There is no standard document other than the one you or an attorney creates it for putting or naming or listing the beneficiaries.
Land trust does not need to be notarized.
Land trust takes the Mastery of Real Estate to the next level...I call it PHD. You be surprised what can be accomplished through Land Trust. Definitely worth digging into it.
I am going to give you a final advise .... if you really want to know it works...when you purchase a property give a copy of it to the title company who is insuring your title and let the Title officer advise you, as to the structure or the ability of the land trust to transfer or sell the property in the future, so you know the Land Trust is valid or is up to code according to the title companies standard...This was a good and free advise, buy yourself an Starbucks coffee with it.
Best wishes and God bless,
