Lease's and agents handling tenant

[Tom King]

I am the son of an investment property owner. My question is this, If I am not the owner of the property or am a licensed broker nor hold a management company of any kind. Can I still manage the property for my mother and sign the lease and follow through with the eviction process if that came to be even though I am not the owner or a licensed broker/manager.

If I can do this?

Can I set up the escrow account for that tenant in my name & theirs and not fall into any legal issues due to the things I am not that I've listed above?

Our current Lease states me as being the "Landlord/Agent" of the property and I would handle all contact with the said tenant.
