Pay or vacate notice

[Charlotte Chew]

My tenant can't pay rent until 5th. I'll give them a "pay or vacate" notice on 3rd. Is there such a notice in BP resources? I didnt see one in BP landlord docs I bought. Does anyone have an example they can share? Im in Bexar Co. TX.  Also, is there a certain way I need to deliver it for it to be admissible in court if I have to move to eviction process? Thanks for any input you have.
