Here's what I found about eviction laws in PA. I hope it helps you! Sounds like he can give you the written eviction but cannot actually evict you without a hearing.

"How Much Notice Does the Landlord Have to Give Me?

It depends whether you have a written lease or just a verbal lease. If there is a written lease, the amount of notice is written in the lease. The lease is allowed to say that the landlord doesn't have to give you any notice at all. It all depends what the lease says.

If you and your landlord just have a verbal agreement about renting your home, you are entitled to get a written notice if he wants to evict you. If the reason the landlord wants you out is because you are behind in rent, or if your eviction is based upon a drug conviction, the landlord must give you 10 days' notice. If you are being evicted for other reasons, the landlord must give you 15 days' notice."

Is There Any Way to Stop My Being Evicted?

If you are being evicted for the sole reason you are behind in your rent, the law allows you to pay the amount of the money judgment up to the time of the scheduled eviction and save your tenancy. You need to pay the money you owe to the constable, not directly to your landlord. Call the District Justice's office to arrange payment. (If the judgment includes rent for the future, consult with a lawyer. This may not be legal.)

If you don't have the money to pay the judgment, you can try to make an agreement with your landlord to make payments over time. If you can come to an agreement, write it down and ask your landlord to sign it. That way you'll have proof if she tries to have you evicted anyway.

You may also be able to file for bankruptcy. You need to consult a lawyer about this option. It may or may not be a good choice for you.

What should I do if I get an eviction notice?

First, if you can, figure out what kind of "eviction notice" it is.

If the paper is from the landlord himself, it is probably a notice he is required to give you before he can file a lawsuit. It might say, "Pay the rent or vacate in 3 days" or the like. If you fail to do either during the stated time, he may then file his eviction lawsuit in court.

If the paper is from the court, it is probably a summons notifying you that the landlord has filed an eviction lawsuit against you. You now have a chance to defend yourself in court - if you act quickly.

If the paper is from the sheriff's or marshal's office, it is probably an order to vacate that the landlord has obtained after suing you. The order will probably state a time by which you must vacate. And you'd better do it. If you don't, some deputies will come by and physically throw you out.

What to do depends on what kind of notice you received.

If the paper is a landlord's notice and you are able to comply with it (e.g., by paying the overdue rent), do it. If the paper is a summons, see a lawyer right away. Don't put it off, because the time limits for responding to a summons are very short - as little as 3 days, and your lawyer might need some of those 3 days to prepare papers for you. If the paper is an order to vacate from the sheriff's or marshal's office, you should probably move your family and your belongings as soon as you can. If you leave anything behind, it might cost you storage fees to get it back. (If you didn't receive a summons before you received the order to vacate, then you should see a lawyer right away, because a lawyer might be able to have the order to vacate set aside on the ground that you never had a chance to defend yourself in court.)
