    Büntetőjog

    Amennyiben Önt letartóztatják, előállítják, akkor egy meggondolatlan mondat vagy ésszerűtlen döntés később az eljárás folyamán óriási hátrányt okozhat Önnek.

    Tapasztalatom szerint már a kihallgatás első percei is óriási pszichikai nyomást jelentenek a terhelt számára, pedig a „tiszta fejre” és meggondolt viselkedésre ilyenkor óriási szükség van. Ez az a helyzet, ahol Ön nem hibázhat, nem kockáztathat, nagyon fontos, hogy már elsőre jól döntsön!

    Védőként én nem csupán segítek Önnek az eljárás folyamán az eljárási cselekmények elvégzésében (beadvány szerkesztés, jelenlét a kihallgatásokon stb.) hanem egy kézben tartva mérem fel lehetőségeit, kidolgozom védelmének precíz stratégiáit, majd ennek alapján határozom meg azt az eszközrendszert, amellyel végig képviselhetem Önt és eredményül elérhetem, hogy semmiképp ne érje indokolatlan hátrány a büntetőeljárás következményeként.

    Védőügyvédjeként én nem csupán bástyaként védem érdekeit a hatóságokkal szemben és dolgozom védelmének stratégiáján, hanem nagy hangsúlyt fektetek az Ön folyamatos tájékoztatására, egyben enyhítve esetleges kilátástalannak tűnő helyzetét is.

    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.
