Harper J. Dimmerman, Attorney at Law

Harper J. Dimmerman, Attorney at Law, holds the highest rating of his peers (AV) with Martindale-Hubbell and has been named as a Pennsylvania Super Lawyer Rising Star on several occasions. He considers Philadelphia litigation and various real estate matters. Legal malpractice is a new area as is personal injury. Mr. Dimmerman lectures to other attorneys on real estate law and ethics topics and is also an adjunct professor at Temple University, where he has taught real estate law topics since 2009. He has served as a Mediator with the Greater Philadelphia Association of Realtors, has been a contributor to “The Legal Intelligencer” and has been licensed as a Realtor with Berkshire Hathaway. He attended Vassar College and graduated cum laude from the University of Miami School of Law. He consults with Pennsylvania law firms as well on real estate law matters and is a leading real estate lawyer in Philadelphia County. 

Mr. Dimmerman (including former attorneys in his office at various intervals) has represented hundreds of clients since 2004. And over the years, he has achieved outstanding results for them. If you are considering retaining Mr. Dimmerman, he can provide testimonials and additional information about his experience as it relates to your specific legal matter, upon request. As for legal fees, which he understands are particularly important at this time in our economy, he is flexible. However, he does not give free legal advice. If the matter is a potential contingency case, he will naturally confer with you. Consultations are also available, which sometimes suffice for smaller matters or situations where full engagement is not feasible.

If you have additional questions prior to making a decision about engaging his services, you are welcome to email him directly: hdimmerman@dimmermanlaw.com or call: (215) 545-0600. Mr. Dimmerman will always respond personally.

If you are suing or being sued, you should act swiftly and in some cases, immediately, lest you run the risk of losing. Although statutes of limitation vary depending upon the case, here are some of the key time limits you must know for Pennsylvania: one year to sue a home inspector, one year for defamation, invasion of privacy and such other related claims, two years for fraud and negligence, four years for breach of contract and six years for consumer protection. Assume the clock begins to run from the earliest possible date, as defense counsel will invariably argue that you waited too long to commence suit or should have been aware of your right to file suit sooner. In other words, any delay, however slight, can make the difference between a recovery, no recovery or in the case of a defense, a costly judgment being taken against you. No attorney-client is formed until a written agreement has been executed.

Areas of Practice and Philosophy

Welcome to Dimmerman PC's website and thank you for visiting, in such a hyper-competitive environment. Mr. Dimmerman understands that you have choices and has the utmost respect for his contemporaries in the legal community. His approach to the practice of law is to treat all clients like family, and ensure they are empowered to make the most cost-effective decisions possible. He strives to empower them with knowledge and also to discourage litigation where a proper cost-benefit analysis indicates a more productive outcome. He understands that law, especially litigation, can be emotionally charged. However, he is committed to not letting the emotion impact his judgment or the necessary dissemination of legal advice. An attorney is responsible for advocating based on the law and the facts, not emotion. In Mr. Dimmerman's opinion, an attorney shall also not give false hope or set unrealistic expectations, especially where litigation is not absolutely necessary. 

Dimmerman PC  has been proudly serving the Philadelphia community since 2004. Mr. Dimmerman is licensed to practice law in Pennsylvania since 2002. 

Harper J. Dimmerman, Attorney at Law, holds the highest rating of his peers (AV) with Martindale-Hubbell and has been named as a Pennsylvania Super Lawyer "Rising Star" on several occasions. He has also owned a title insurance company and served as a Mediator for the Greater Philadelphia Association of Realtors. He was previously a licensed Realtor with Berkshire Hathaway as well, which gives him yet even more insight into real law transactions and litigation. He considers Philadelphia litigation and various real estate matters. Legal malpractice is a new area as is personal injury. If he accepts either a legal malpractice or personal injury case, he will likely co-counsel with another attorney possessing more experience in those particular areas, just to ensure the client is as safeguarded as possible. Law has become a highly specialized business, with such obvious examples as domestic relations, tax, zoning and landlord-tenant. Even within a given practice area, the sub-specialties have rendered the practice of law even more complicated. For example, medical malpractice is a highly specialized area within the personal injury arena and those properly versed in medical malpractice should be vetted (this is not Mr. Dimmerman).

He has litigated defamation cases, residential and commercial landlord-tenant matters, confession of judgment cases, commercial landlord-tenant litigation, security deposit disputes, seller disclosure fraud, consumer fraud, home inspector liability cases, breach of contract matters, partition actions, adverse possession matters, boundary dispute litigation, specific performance litigation, commercial litigation disputes, sheriff's sale matters, tax redemption litigation, mechanics' liens actions, condominium litigation, easement litigation, declaratory judgment actions, amongst others over the years. He has provided foreclosure defense aid, has engaged in workouts with residential mortgage lenders and has been representing a declarant in Northern Liberties for several years. He has assisted realtors with commission dispute issues and settled a large, complex case on behalf of many homeowners in a well-known Philadelphia condominium building. He recently represented a commercial property owner in a dispute with a commercial brokerage firm. He has arbitrated a 203(k) contractor dispute and has represented parties at mediations. He recently represented a real estate agent, who was sued in a personal injury case, where it was alleged that her management of the property created liability. He represented a home inspection company in a similar personal injury context. He has assisted borrowers with deeds in lieu of foreclosure, timeshare issues and condominium disputes as well.

He does not represent lenders generally, does not handle real estate tax appeals and no longer handles any deed transfers. He does not handle "estate" matters, which are obviously quite different from real estate matters, despite both areas sharing the word "estate." He no longer handles domestic relations and bankruptcy, as he has in the past. He is not interested in working with any client who attempts to interfere with his representation of them. He tends to limit his litigation practice to Philadelphia County. He no longer practices in the State of New Jersey. If Mr. Dimmerman refers you to another lawyer/firm, he reserves the right to accept a referral fee in accordance with the Rules of Professional Conduct, which is common practice. Of course, no attorney-client relationship is formed by merely contacting him; a written representation or consultation agreement must be executed.

His proudest victory was a Philadelphia Housing Authority (PHA) appeal, which he tried before a Philadelphia jury and was able to keep a lovely person in her home. As a result of the joy experienced in litigating that appeal, Mr. Dimmerman now offers low fee and even pro bono representation for those matters, to be decided on a case-by-case basis. As for transactional matters, Mr. Dimmerman has drafted residential and commercial contracts and has an intense mastery over real estate law topics. He truly enjoys protecting the interests of a buyer or seller in a deal and will not let a realtor's myopic focus on commissions interfere with your legal rights, which includes ensuring that your deposit is not inflated, that you understand the true condition of the property before settlement (including receiving the Seller's Disclosure Statement before the offer is submitted) and that you are not stuck in an unfortunate deal, despite having believed the contingencies would offer you a simple means of extricating yourself. In Pennsylvania, an executory contract is entirely binding and enforceable. His prior experience as a title insurance company owner, Realtor and having had a contract with the City of Philadelphia (reviewing zoning hearing transcripts and drafting Findings) gives him the competitive edge you deserve, as does the fact that he actually litigates real estate disputes. Would you want a non-litigator drafting agreements, if that person has a harder time foreseeing the possible litigation issues stemming from that very same contract? The choice is yours.
