Ask an Property Solicitor. Get an Answer ASAP.
Hi, I'm Lea and I have reviewed your query.
Are you a residential landlord - i.e. living in the property with the person you have rented to?
Do you have a copy of the agreement signed? If yes, kindly attach it.
Please bear in mind this is an email service and not a live chat so responses may not be instantaneous. I am not available for calls, but in all cases it is very likely you can be helped online.
Is the property you are renting out self contained, or is it shared space?
But it is in the same building as your own accommodation as you state they used your bathroom. Do they share any other facilities - entrance, hallway, kitchen etc?
I am not available to call you - but your request is open to other experts.
If you want to continue here, we can.
