Senat is one
of Liechtenstein’s oldest
and most traditional
trust businesses

Our roots go back to 1936 when Mr. Ludwig Hasler, former head of Liechtenstein Tax Authority, established the fiduciary business Treuhandbüro Hasler focusing on offering fiduciary services and providing tax and legal advice.

Today, the grandson of Ludwig Hasler, Dr. Markus Hasler is the managing partner of Senat AG and the business offices remain located at the same address; Egertastrasse 17, Vaduz.

As Liechtenstein has developed as a financial center so has Senat AG and expanded its services. Regardless of whatever changes that have occurred during the years Senat AG still adheres to the founding principles of Mr. Ludwig Hasler, competence, transparency and trust.

As a direct result of this many of Senat AG’s clients are long-term clients and the relationships often date back several decades. Senat AG takes pride in being able to assist families and individuals over several generations and to provide assistance and valuable advice in order to preserve wealth and to find solutions that benefit the beneficiaries long-term.

We do not store confidential information electronically.

We have rigid policies with regards to privileged information. Only key employees are given strict authorization to access client files.

and customer due

Senat AG is fully compliant with local legislation and as such performs up-to-date customer due diligence on all of its partners and clients. Having said this, Senat AG is careful to never overstep what is required by law.

Tax conformity
and undisclosed

As Senat AG is fully compliant this also means that it is only able to engage prospective clients that are tax compliant and that have sufficient documentation with regards to origin of wealth. Senat AG wishes to clearly state that it cannot and will not assist individuals and/or corporate clients that seek advice that effectively constitutes tax evasion.

Is asset protection
legal or morally

Asset Protection stems back several hundred years and the earliest documentation we have is when individuals travelled to the Holy Land. It was recognized that this was a highly perilous voyage and as such, before embarking on it, one should set his/her affairs in order. This was often done through the use of Trusts in Anglo Saxon countries and through Foundations for individuals residing on the Continent.

Wise business men reason the same way nowadays before they engage in complex investments and projects by separating private wealth from corporate assets. This ensures a certain financial stability not only for the business man/woman but for his/her family. It is also a proven fact that wealth that is structured, wisely and carefully invested, in a tax efficient manner lasts longer than when wealth is held privately without any restrictions.

Asset Protection in itself has never been seriously questioned and estate planning just as tax planning is not only allowed but highly advisable.

Asset Protection structures enable individuals to not only structure their wealth and to protect it but it gives them a platform to set out certain rules and to ensure that the wealth is used in ways that truly benefit themselves and their families.
