English to Polish Law/Patents Law: Contract(s)

Jak nazwać podpunkt Notices and service, w któym mowa jest o "Any notice terminating this Agreement or indicating that a breach of its terms has occurred shall be in writing and may be delivered personally or by letter, or sent by prepaid first class post or recorded delivery despatched by one party to the other at its address as set out below..."

Z góry dziękuję za pomoc :)
