lege artis zug
The Latin expression de lege artis [lex, legis = law; ars, artis = art] means “by the rules of the art” or “generally acknowledged rules of the art”.
For us, lege artis means providing our clients with first-class, professional and substantiated services “by the rules of the art of law”. That means doing high-quality work that is consistently focused on results and goes beyond classic legal advice.
In carrying out our briefs, we are committed to meticulous legal advice and prudent representation, taking into account the jurisprudence (of the highest court) and recognised doctrine which guides the way in legal practice.
Our firm
We are a renowned law and notary’s office with a long tradition in the heart of the financial hub that is Zug. Since being founded in 1978 as Hausheer & Partner and later Swisslegal HPLAW ZUG, we have established ourselves in Zug and the surrounding area as a competent law and notary’s office which provides a wide range of legal and interdisciplinary services in legal advice and litigation. We changed our name to lege artis zug – Rechtsanwälte und Notare in 2024.
Our clients consist of both companies and private individuals from Switzerland and overseas who appreciate both our streamlined structure and the personal, interdisciplinary approach we take to legal advice, thanks to which we can develop holistic, tailor-made solutions.
We cover corporate law services in commercial and company law, corporate governance, contract law and notarial services, as well as marriage and inheritance law, succession planning, execution of wills, liability and insurance law and (financial) criminal law.

Our philosophy
The attorneys at law at lege artis zug offer both private individuals and companies professional legal advice and representation, and can also conduct cases for you before public authorities and the courts in Switzerland. With an analytical approach to our work, good time management and a focus on feasible and financially sensible solutions, we can offer you an efficient, client-specific and solution-oriented way of working.
We see ourselves as all-rounders with proven expertise and an eye for detail – all while never losing sight of the bigger picture.
Our goal is always to establish a long-term relationship based on trust and success.
Our legal work starts by working together on an in-depth analysis of the current situation, taking into account various aspects and dimensions – this is the only way to find new opportunities for solutions or success.
In the case of legal conflicts, we should also always consider a mutual, expedient resolution between the parties. We and our clients therefore also regularly look at potential ways to settle matters out of court.
Where this is not possible, we will represent your interests before public authorities or the courts with just as much expertise and dedication. Our years of forensic experience cover everything from routine cases to complex legal matters.
We look forward to hearing from you.
