Adherence to explicit terms is critical in contract law. Any modifications or demands for additional assurances must be consistent with existing contractual agreements. Imposing unilateral conditions not stipulated within the original contract can constitute a breach. Both parties must agree to any amendments for those changes to be legally binding.
For example: If a lease agreement allows for renovations with landlord consent, a tenant cannot unilaterally decide to renovate without such consent — doing so would violate explicit contract terms and could lead to legal action.
