Desk with contract

Contract Law

Careful legal support in drafting, reviewing, and enforcing contracts.

In the field of contract and property law, I stand by your side and advise you comprehensively on the respective legal transactions. This includes drafting, reviewing, and enforcing contracts, such as:

In detail

Contract drafting and review

Whether a purchase, work, agency, lease, loan, or cooperation contract: I draft agreements so that they reflect your interests and are at the same time acceptable to the other side. The decisive points are those that rarely stand out in day-to-day business but determine everything in the event of conflict — description of services, deadlines and dates, warranty, liability and its limitation, contractual penalties, termination and exit options, place of jurisdiction, and applicable law. If a draft contract from the other side is already on the table, I review it for gaps, unclear wording, and one-sided clauses, and show you what you would be committing to — before you sign.

Contract negotiations

Many contracts are shaped not at the desk but at the negotiating table. I support you in negotiations — in the background as an adviser to your position or as active lead negotiator — and ensure that the results achieved are subsequently reflected in clean legal wording. The point is not to push for the maximum, but to find a solution that lasts and does not burden the business relationship. Where it makes sense, we safeguard intermediate steps with letters of intent, preliminary contracts, or confidentiality agreements.

Adaptation of existing contract frameworks

Contracts age. Business models change, prices and services evolve, legal requirements are adjusted — and suddenly the agreement concluded years ago no longer matches day-to-day reality. I review existing contract frameworks, general terms and conditions, and contract templates for how up to date they are, and prepare addenda, supplementary agreements, or revised versions. For companies, I also draft standardised model contracts that reduce recurring effort and ensure a uniform contract practice.

Assessment of legal risks

Before every signature the same question arises: what can go wrong — and who then bears which consequences? I analyse your contract situation for its economic and legal risks, assess liability and warranty consequences, and set out the options for action with their respective opportunities and drawbacks. You receive a clear, understandable assessment as the basis for your decision — not an expert opinion that only specialists can read.

Frequently asked questions

FAQ — Contract Law

Whenever substantial financial, personal, or business obligations are involved — purchase contracts, work contracts, service agreements, shareholder agreements, senior-level employment contracts. A review in advance is significantly cheaper than a dispute afterwards.

Liability limitations, contractual penalties, jurisdiction and choice-of-law clauses, non-compete clauses, termination rights, and performance deadlines are, in my experience, the provisions that most often lead to disputes later. I insist on reading these particularly carefully and tailoring them to your specific situation.

Through clear, precise wording instead of generic formulas. Through realistically balanced provisions instead of one-sided clauses that would be contested anyway in case of dispute. Through clean definitions of services and consideration. And through fair but enforceable safeguards for cases of conflict.

Depending on the type of contract and the breach, various legal remedies are available — rectification, substitute performance, damages, contract termination, unwinding. I review the legal position, clarify your options, and support you in enforcement, whether out of court or in proceedings.

In principle yes — through addenda, supplementary agreements, or entirely new versions. Both parties must consent. In long-term contractual relationships (leases, work contracts during construction phases, consultancy contracts), it is common to update regularly so that the contract reflects the practice being lived.

What must be clarified before a contract negotiation?

Marie Anouk: What must be clarified before a contract negotiation?

Antoine F. Goetschel: Laozi wrote: solve problems before they arise; bring order before chaos sets in. One should think in advance about the ultimate purpose of the contract — why am I entering into this relationship, to what end? When the focus falls entirely on the contractual provisions — and we have gone from one- or two-page contracts to documents of 50, 60 or 100 pages in the American tradition — what should be resolved often is not. Trust should come first, then the purpose. The clearer and simpler a contract, the more it signals that the parties want to be part of the solution, not the problem. Recently I concluded an agreement on a major project with a handshake. Because I trust the person, that handshake means more to me than a 50-page lawyers' contract with jurisdiction in Gibraltar and governing law in America — or Uganda.

When is a contract legally valid and when is it not?

Marie Anouk: When is a contract valid and when is it not?

Antoine F. Goetschel: Law is, in essence, form. Lawyers look first at whether the required form has been observed: was land sold without notarial authentication? Then the contract is void. Lawyers love to check the form first — is a signature missing, is the date absent? «I want out of this» — colloquially, we look for the hair in the soup. A contract is also void when the parties had entirely different understandings of its basic subject matter — I wanted sugar, you delivered salt, and because both look similar a false delivery occurred: that raises the question of mistake. The fundamental principle is that contracts must be honoured — this was already true in ancient Roman law. Breaking a contract one has already partly performed is not easy, especially when the other party insists on it.

Which clauses carry the greatest risk?

Show transcript

Marie Anouk: Which clauses carry the greatest risk?

Antoine F. Goetschel: Clauses on governing law — when a Swiss or European contract applies American or Chinese law that the parties have no knowledge of and that has no connection to the subject matter. When the jurisdiction clause requires bringing claims in a completely different location: I recall a major case in Canton Lucerne where proceedings had to be brought in Gibraltar even though substantial sums were based in Lucerne. Beyond that: if I cannot explain a clause to a friend in plain language, or if behind the façade of grandiose terms something lurks that I do not actually understand, I would be sceptical. Terms like «compliance» mean different things to different people. If I do not understand what was agreed, or what I can demand from whom, under what conditions and with what guarantees, I would ask questions and only enter the contract once I know precisely what I am committing to.
