An interview with lawyer Ornucha Roongruangnoparat explores critical legal frameworks for SME co-founders and business partners. Key takeaways: (1) Partnership agreements must clearly define contributions (cash, labour, assets), timelines, and operational structure using the What-When-How framework; (2) Digital assets and social media rights default to the creator unless explicitly assigned in contracts; (3) Digital evidence (chat logs, payment slips, emails) carries significant legal weight in civil disputes; (4) Document all agreements in writing, especially after verbal calls, to prevent blackmail or disputes. Early legal consultation and mediation are preferable to litigation for preserving relationships and reducing costs.
