Our Los Angeles Eviction Attorneys recently faced an issue with proving a monthly rent amount in an eviction trial wherein there was no rental agreement and most rent payments were made in cash without receipts. In such a situation, all the tenant has to do to call into issue the accuracy of a three-day notice is to testify that the monthly rent amount is something other than what is listed in the 3-day notice. Due to the technical nature of an eviction trial, such ambiguities are very difficult to overcome.
If you are a landlord and are renting property pursuant to an oral agreement, you are best served with executing a written lease agreement regardless of the relationship with the tenant or the duration of the tenancy.
