Is it ok for landlord to call family members and tell them you are late you rent

It all depends. Are any of the family members guarantors on the lease? If so, of course the landlord has the right to notify them of your delinquency. If they are not listed as guarantors, you might have a claim, for among other things, invasion of privacy.

A landlord's calls is not the same as a creditor's calls, but there are some limits to what they are allowed to do to collect what they are owed. Whether the landlord's call to family is improper depends on the contents of your lease. If you are unsure after you look at your lease, you should consider showing it to an attorney for an informed opinion. Hope this helps. ~ Kem Eyo
