Question for those who have a series LLC

[Jennifer M.]

I hold my properties in a Texas series LLC. Up until this point, I have done nothing formal to establish a new series each time I purchase a new property. I just have the property titled in the name of the new series. Generally, the title companies have no problem with this. But, lately I have had two title companies ask for proof of existence of the series. For those who also use a series LLC, what type of documentation are you putting together when you buy a new property and set up the new series? Thanks!
