How we can assist you with contract law

Fricker Füllemann Attorneys at Law advise individuals and businesses on drafting, reviewing, amending, and terminating contracts. In cases of breach of contract, we assist with enforcing or defending against contractual claims, as well as in out-of-court and court proceedings.

Contract Review and Drafting

We review and draft contracts with regard to services, compensation, liability, warranties, termination, and other key provisions. We identify any unclear clauses and legal or financial risks before the contract is signed.

Sales Contracts and Warranties

We provide legal advice on private and commercial sales contracts, as well as on disputes regarding defects, warranted characteristics, rectification, price reduction, rescission, and damages.

Breaches of Contract and Disputes Over Claims

If an agreed-upon service is not provided, is provided late, or is provided in a substandard manner, we will review the resulting claims. We will enforce claims or defend against unfounded demands for payment and damages.

Termination, Withdrawal, and Rescission

We determine whether and under what conditions a contract can be terminated with or without notice, rescinded, or reversed. In addition, we assist with the legally sound declaration and the subsequent settlement.

Articles of Association and Business Agreements

We provide legal advice on articles of association and other agreements between shareholders, business partners, and companies. This includes matters related to termination, withdrawal, breaches of contract, and financial claims.

Documented Procedures in Contract Law

Selected cases illustrate how contractual claims can be assessed, enforced, or defended against. The outcomes depend on the specific terms of the agreement, the evidence, and the circumstances in each case.

Full comprehensive coverage despite electronically recorded speed

A comprehensive auto insurance company reduced its benefits due to alleged gross negligence, basing its decision on vehicle data retrieved electronically. After the evidentiary value of that data was called into question, the insurance company withdrew the reduction and paid an additional CHF 39,622.10.

Claim for CHF 65,000 Rejected Following Termination of a Partnership Agreement

Following the termination of a partnership agreement, a property owner demanded payments totaling approximately CHF 65,000. The Zug Cantonal Court upheld the validity of the termination and dismissed the claim to the extent that it was admissible.

Claims for damages in the mid-six-figure range settled without payment

Following the breakdown of a business partnership, numerous contractual allegations and claims for damages were made. The dispute was fully resolved through a settlement without any payment having to be made.

Here's how we handle contract-related issues

Contract disputes require a thorough review of the agreements, the actual performance of the contract, and the available evidence. We assess the initial situation and tailor our approach to achieve your legal and business objectives.

1. Review the contract and the initial situation

We clarify what agreements are in place, what services have been provided, and where there are disagreements. In doing so, we also review contract amendments, supplementary agreements, and relevant deadlines.

2. Review documents and evidence

We analyze contracts, terms and conditions, correspondence, invoices, payment receipts, and other documents. This allows us to assess which claims can be substantiated both legally and factually.

3. Identify Requirements, Risks, and Procedures

We review the enforcement or defense of contractual claims and identify the legal, evidentiary, and economic risks. We then determine the next appropriate steps.

4. Negotiating and Conducting Proceedings

We handle communication with the other party, conduct settlement negotiations, and represent you before arbitration tribunals and courts as needed.
