Placing a deposit is the cheapest moment to make a mistake, and the one almost nobody takes advantage of. You leave a small amount, sign a one-page sheet, and everything seems reversible. But the deposit freezes the price and opens a negotiation in which every document you didn’t ask for beforehand becomes harder to ask for afterward. Here is the list of fourteen documents worth having in hand before reserving a property in Tulum, in the order we would ask for them.
About the property
1. Deed registered with the Public Registry. Not a plain copy or a promise: the deed bearing the registration stamp. It shows who the legal owner is and that what is being sold is what the paper says. If the seller doesn’t have it, they can’t sell yet.
2. Certificate of freedom from liens. It states whether the property carries mortgages, attachments, or any other registered encumbrance. Ask for a current one, because a certificate from a year ago tells you nothing about what has happened since.
3. Property tax (predial) receipt, paid up to date. With the current year’s payment. Overdue property tax is inherited along with the property.
4. Certificate of no outstanding water debt. This is a document that gets forgotten and can hold surprises, especially in properties that have sat empty or been rented seasonally.
5. Land use certificate. It is essential in Tulum: the coastal zone and some areas have restrictions on density, height, and use. What matters is not only that the property exists, but that it can be used the way the buyer plans to, for example for short-term rental.
About the building or development
6. Construction permit and notice of completion of works. In a building that has already been delivered, they confirm it was built with a permit. In a presale, a valid construction permit is the minimum you should ask the developer for before moving a single peso.
7. Approved plans. Compare them against what you see or what is promised. Square meters, terrace, parking, and storage: what is being sold and what is on the plan must match.
8. Deed establishing the condominium regime and its bylaws. It defines what is private, what is common, how much you pay in fees, and what you are allowed to do. If you plan to rent, the bylaws may prohibit or limit it.
9. Certificate of no outstanding maintenance fees. The administration should certify that the unit owes nothing. A debt in fees passes to the new owner in practice, even if there is debate over who should pay it.
About the seller
10. Official ID and the seller’s tax information. And, if a company is selling, its articles of incorporation and the power of attorney of whoever signs. You need to confirm that whoever promises to sell has the authority to do so.
11. If there are co-owners or a spouse, their written consent. A property with two owners can’t be sold by just one. It is a classic reason deals fall apart after the deposit.
About the deposit and closing
12. Written deposit agreement. With the price, the identified property, the deadline, what happens to the money if either party doesn’t go forward, and who receives it. A receipt without conditions protects no one.
13. Draft of the purchase-sale contract or promise to sell. Asking for it at the deposit stage lets you review calmly what you are going to sign, rather than receiving it the day before. If the purchase will go through a trust (fideicomiso), also ask for the draft of that instrument and for how the permit is processed with the Ministry of Foreign Affairs (Secretaría de Relaciones Exteriores). We have two articles on why the trust yes and the nominee no and on how a deed is verified.
14. Payment details and tax receipt. In whose name the money is transferred, from which account, and that an invoice or formal receipt is issued. Never to an unsupported personal account, and always with proof of each payment.
Which ones are non-negotiable
Not all of them carry the same weight. If 1, 2, or 10 is missing, you don’t place a deposit: without a registered deed, without knowing whether there is a lien, and without knowing who signs, everything else is decoration. Documents 3, 4, and 9 can be resolved with a payment or a discount, as long as it is known in time and put in writing. Items 5 and 6 decide whether the use you plan is even possible. And 12 is the one that decides how much risk your money carries while everything else is completed.
For an ejido property or a lot without a deed, the list changes completely: there, the first thing to ask is that the regime be full ownership (dominio pleno). That is a different conversation, and worth having with a lawyer before discussing price.
What we see in searches
We review what people type into Google and end up on inversionesdemexico.com. From July 19 to October 17, 2026, 65 queries containing “Tulum” added up to 302 impressions and zero clicks. It is a modest figure and we give it as it is. What it shows is that Tulum buyers are still searching blind: few searches mention documents, and nobody knows what to ask for until they are already sitting across from the seller. That is why we wrote this list.
If you are buying in presale
The list changes shape: there is no deed for the unit yet and no fee certificate, so the weight shifts to the developer. Ask for the deed to the land in the seller’s name, its freedom from liens, the valid construction permit, and the draft contract with the delivery dates and the penalties for delays. If the land has a mortgage, ask how the unit is released when it is deeded to you. It is the question that makes people most uncomfortable and the one that protects you most.
How to use it
Print it or copy it into a note and check off each document as it arrives. They don’t all have to arrive on the same day; what matters is that the deposit is made with the complete list in view, not under the seller’s urgency. A serious seller has them or can get them within a few days. If every document turns into a fight, you already know what the rest of the transaction would be like.
If you are evaluating a property in Tulum and want us to review the documents before you leave a single peso, write to us. We will tell you which ones are missing and which ones can be required before the deposit.
