Assistance provided by us to public entities covers all stages of contract formation namely, the opening of pre-contractual procedures and drafting of the procedure papers, analysis of bids and contract awarding and contract performance based on a previously made draft.

In legal assistance provided by us to private entities we are actively involved during bid preparation, in the drafting of information requests, advising during preliminary hearings and on the negotiation of the contract draft.

Our assistance is not restricted to the pre-contractual stage. Services include the contract’s performance and termination stages and, whenever necessary, the litigation stage.
