About Sander Hartog MRICS

My qualities? I solve the problem; practically, quickly and by mutual agreement. I think outside the box by also giving advice beyond the legal context. I am a good listener so that I can discuss problems, opportunities and possibilities.

Sander Hartog is a partner and works from the Alkmaar office. He specialises in real estate (administrative and civil law, contracting of work, contract formation and property development). Always looking for the best possible solution, and with an eye for the client's interests, he is manifestly a reliable and driven lawyer. Parties like landowners, contractors and property developers appreciate his honest and thorough advice.

Sander is a reliable, committed and driven lawyer, with great perseverance and the will to win every time. While working towards this - partly due to his training as a mediator - he does not lose sight of the other party's feelings and interests. "Therein often lies the key. By exploring exactly what the other party's sensitivities and interests are, you can often arrive at solutions that both parties can get on with. This quickly resolves the dispute and allows the parties to move on again at the lowest possible cost. A business owner has no desire for lengthy legal arguments, memos and proceedings. He has a problem that needs to be solved so that he or she can move on again." Furthermore, Sander places high value on reliability and honest, sound advice. He does not tell his client fairy tales, but goes for the best possible solution in the given circumstances.

Sander's broad knowledge in the field of real estate and his supervisory board memberships make him an excellent discussion partner for developers, landowners and contractors regarding property development (zoning plans, contract formation and so on), real estate operation, contracting of work and commercial leasing.
