Our own lawyer told me this. We got to know each other over many years. He told me that the worst part of being a lawyer in Puerto Vallarta was there was not another single lawyer he could trust. He spent six years successfuly litigating our case, battling four time wasting appeals, against a well known crooked property owner and a crooked Notary, only to lose it in the end by another crooked Notary. DO NOT BUY PROPERTY IN MEXICO UNLESS YOU CAN AFFORD TO WALK AWAY. There are too many goalposts constantly moving by government or powerful individuals, or both. The real estate lady who writes about historic properties in PV told me that nearly every desirable property she knew of was in a quagmire of title disputes, none of which your Notary will tell you about. Ask someone who knows, about all the arbitrary changes the new Presidente has recently made. No other country would turn over property rights and taxation issues in such a dictatorial way. And in Mexico, blood is always thicker than water when dealing with foreigners. Always.
Our lawyer's son was studying law, to take over his father's firm, but he too began to see all the necessary corruption there, and decided not to become a part of it. How many lawyers have been murdered in PV over the past 10 years? At least 5 I think.
