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 focussing on management the of intellectual property rights and providing tax and legal advice.

Today, Senat group of companies encompasses a wide range of services and several jurisdictions including a full-fledge office in Dubai (United Arab Emirates) and representative offices in Zurich (Switzerland). In the Principality of Liechtenstein, Senat is present at Egertastrasse 15-17, Vaduz, the historic site of Treuhandbüro Hasler. Dr. iur. Markus Otto Hasler followed in the footsteps of his grandfather Ludwig Hasler and acts today as member of management in many of the group’s companies.

and digital data

We commit to confidentiality and recognize the threat of digital technologies.
We prefer paper to digital media. It is our corporate policy to provide each staff member with two computer stations, with and without internet access, and keep or process no client related information on stations connected to internet.
We do not store confidential information electronically.
We have rigid policies to access authorizations for staff mem- bers.

and customer due

We recognize that AML and CDD should serve the client and not the other way around. We keep our AML obligations, but we do not encourage formalism and paper for the sake of paper.

Tax conformity
and undisclosed

We do not parent our clients on obligations of their own. However, we do not offer solutions which do not work. For instance, an asset protection «plan» which can be compromised by unresolved tax issues is a waste of time.

Is asset protection
legal or morally

Asset protection is legal ex definitione, being a pre-litigation plan aimed to put one’s assets beyond the reach of adversaries.

It requires a detailed and most careful legal scrutiny of the facts from the perspectives of all involved jurisdictions. A good asset protection plan will be respected by the court if challenged in a litigation. It is therefore always legal.

Individuals with assets in different countries often have a broad leeway for structuring their wealth, and depending on the chosen path such individuals’ potential creditors will find themselves in a more or less favorable situation.

However, no one is obliged to arrange his affairs in such a way as to best please one’s potential future creditors, or provide them with the most efficient enforcement opportunities. There can be nothing wrong with choosing a legal pattern in which one’s assets are protected in a better or best extent permitted by law.
