Állandó, komplex képviselet

Még mindig él a cégvezetőkben az a tévképzet, hogy ügyvédet választani egy vállalkozás vagy társaság számára elegendő akkor, ha bíróságra kell menni.

Semmivel sem árthat annyit cége nehezen elért sikereinek, mint, ha megfelelő jogi képviselet nélkül hagyná vállalatát!

Irodámban egyedi megállapodás alapján lehetőség van állandó megbízás megkötésére, melynek keretében folyamatosan együtt tudunk működni, bármilyen felmerülő kérdés probléma esetén kereshet személyesen vagy telefonon is.  Ennek nem csupán az az előnye, hogy Ön állandó ügyfelemként előnyt élvez majd időpont-egyeztetéskor, hanem ennél sokkal fontosabb, hogy az Ön cégét megismerve személyesen kezeskedem arról, hogy tevékenysége folyamatosan a törvényesség talaján maradjon. Megismerve az Ön cégének munkafolyamatait és folyamatosan együttműködve vezetőséggel a jogi tudást igénylő helyzeteket nem csupán utólag tudjuk kezelni, akkor, amikor már „ég a ház”, hanem előre felkészülve gondoskodhatunk arról, hogy Önt ne érhesse meglepetés.
