Tenant lease review

Your landlord handed you a lease. Is any of it legal in Massachusetts?

Upload it. We'll tell you what's fine, what's questionable, and what your landlord isn't allowed to put in writing in the first place.

Plain English

You should not need a law degree to sign a lease.

Massachusetts has some of the strongest tenant protections in the country, and a lot of landlords either don't know the rules or hope you don't. Clauses about last month's rent, security deposits, late fees, as-is conditions, and waivers of your rights show up in leases all the time, and a surprising number of them are unenforceable or outright illegal.

We read the fine print so you don't have to.

What we check

The clauses most tenants miss first.

Illegal fees and deposits

The rules about first, last, security, and broker fees are strict, and they are broken constantly.

Illegal clauses

Waivers of your right to sue, as-is habitability disclaimers, automatic eviction language, and forced arbitration.

Questionable clauses

Terms that are technically legal but aggressive, and worth negotiating before you sign.

Things you might miss

Auto-renewal, guest policies, maintenance responsibility, notice requirements, and other fine print.

What's actually fine

So you know the whole lease is not a trap and can focus on the language that matters.

You'll get a plain-English report that flags every issue with a severity level, explains what the law actually says, and tells you what to do about it.

Frequently asked

Questions before you upload.

Is this legal advice?

No. LeaseLock analyzes leases against Massachusetts law and flags problems, but we are not your lawyer and this is not legal advice. If you are in a dispute or facing eviction, talk to a licensed attorney.

Does this work for any type of rental?

We are tuned for Massachusetts residential leases: apartments, houses, rooms, and roommate situations. We do not currently review commercial leases, short-term rentals under 100 days, or leases governed by other states' law.

What if my lease is on paper?

Snap a clear photo of each page with your phone. We will extract the text. If the photos are too blurry to read, we will let you know and refund you.

I already signed. Is it too late?

No. A review can be just as useful after signing because it tells you what your landlord likely cannot enforce against you and where you may have leverage if something comes up.

How is this different from having a lawyer look at it?

A lawyer will cost more and usually take longer. We cost $29 and aim for ten minutes. We are the right choice when you need a quick read on whether your lease is fair; a lawyer is the right choice when you are in an active fight.

Can my landlord see this?

No. The report goes only to you. What you do with it is up to you.

What if the report finds nothing wrong?

Then you have peace of mind, which is the whole point. You can also share the report with roommates or friends considering the same building.
