Amme, the most urgent thing in your question is not what your rights are. It is the clock. Pennsylvania's limitations period for breach of a written contract is generally four years. Your addendum is from 2016. If the breach occurred years ago and the clock started then, the window to sue on it may already be closed, and every month you spend gathering opinions instead of sitting with a lawyer makes that worse. There are arguments that can extend or restart it, for example a continuing breach, or a discovery rule if you could not reasonably have known, or an obligation that recurs rather than one that was broken once. Those arguments are fact-specific and they are exactly what a lawyer is for. Please treat this as a this-month problem rather than a someday problem. The thread is right that being named an intended beneficiary matters. An intended third-party beneficiary can generally enforce a contract they did not sign. But there are two questions underneath that, and they decide everything: Was the addendum recorded? This is the one I would check first, and it is something you can do yourself this week at the York County Recorder of Deeds. If the addendum, or a memorandum of it, was recorded against the property, it likely runs with the land and binds whoever owns it now. If it was never recorded, you may only have a claim against the original parties personally, and a current owner who bought without notice may not be bound at all. Same document, completely different outcomes. Who owns the property now, and did they take with notice? If ownership has changed since 2016 and nothing was recorded, that is a much harder case, and it is a different case, aimed at different defendants. When you see the attorney, bring these, organized: The 2016 addendum and the underlying purchase agreement it modified, complete, all pages. The deed and any recorded documents for both parcels, which you can pull at the recorder's office. A written timeline: what was promised, what was performed, when performance stopped, and when you first knew. Every receipt for the work you have been paying for out of pocket, totaled. That total is your damages number and it is what makes the case worth pursuing or not. Every piece of correspondence where you asked anyone to perform, especially anything in writing. That is what shows you did not sit on your rights. Ask the attorney about the remedy menu, because the answer is not only money. Specific performance, meaning a court ordering the other side to actually do what they promised, is often the remedy that matters most when what you want is the work done and the use restored. There may also be a declaratory judgment path, meaning asking the court to declare what the rights are going forward, which can be cheaper and faster than a damages suit and can be worth more if this is an ongoing arrangement. Two practical notes. Find a commercial real estate litigation attorney, not a residential closing attorney. This is a contract enforcement matter involving commercial property, and it is a different specialty. And if the York County Bar Association has a lawyer referral service, that is a reasonable starting point for finding someone in the right practice area quickly. I want to be straight with you about my limits. I am a real estate professional, not an attorney, and I have not read your addendum. Everything above is a map of the questions to ask, not an opinion on your case. Given the limitations issue, an actual consultation this month is worth far more than any answer you will get on a forum, including mine. West York is not my market, I am Zoltan Peresztegi, and I work Los Angeles and the South Bay, so I am not the right person to help on the ground here. But I would not let this sit another month.
