José Bolio Halloran

He represents the buyer. Only the buyer.

José Bolio Halloran is a Mexican attorney based in Mérida, Yucatán, who represents foreign buyers of real estate in Mexico, and never the developer, broker or seller on the other side. He founded PeninsuLawyers in 2017, after eleven years at Petróleos Mexicanos (Pemex) that ended with him as Deputy Manager of Legal Services for its Southeast Region and two years running his own consultancy, and he has worked as in-house legal director for a Mexican real-estate developer, so he knows how developer contracts are written. He is the author of The Foreign Investor's Legal Guide to Riviera Maya Real Estate and spoke on the main stage of APEX 2025, America's Property Exhibition, in Miami.

About José

A lawyer who used to sit on the other side of the table.

José founded PeninsuLawyers in Mérida in 2017 on one conviction: a foreign buyer in Mexico deserves a lawyer who takes nothing from the developer, the broker or anyone else across the deal. That is still the only side he works for.

He knows how the other side works because he has sat there. José has served as in-house legal director for a Mexican real-estate developer, drafting and negotiating the presale and purchase contracts his clients now bring to him. It is why he reads a developer contract for what it leaves out, not only for what it says.

His career began inside two of Mexico's largest institutions. He joined Televisa's legal team in 1999, then spent eleven years at Pemex negotiating public-works, procurement and media contracts for the oil industry, before serving as Deputy Manager of Legal Services for the company's Southeast Region.

Today he leads the firm's developer disputes, PROFECO consumer claims and pre-purchase reviews, and writes every article published on peninsulawyers.com. He meets clients in English or Spanish, by video or in person in Mérida.

Buyers only

No developer, broker or seller retainers. No referral fees from the other side. The conflict never starts.

Read what's missing

Developer contracts are written to be signed, not read. He looks for the clause that isn't there.

Plain answers

Every client gets the legal position in plain English, with the risk named and a recommendation.

Main-stage presentation

APEX 2025 — America's Property Exhibition (2nd edition)

“Structuring for Success: Legal Frameworks for Profitable Real Estate Development in Mexico”

September 18, 2025Miami Beach Convention Center, Miami Beach, Florida

Speaking to an international audience of investors, funds and developers, José argued that legal integrity is a product feature: a project with a murky legal foundation is a high-risk, inferior product, and a developer who builds on an impeccable structure is selling something better.

01Preemptive due diligence: title, permits and zoning cleared before a single unit is sold.
02Corporate architecture: when a fideicomiso (bank trust) fits and when a Mexican corporation does.
03The new compliance paradigm: NOM-247 consumer protection and Mexico's 2025 anti-money-laundering reform.
04“The Trust Premium”: developers who urge every buyer to hire independent counsel signal a confidence no brochure can.
