彩礼在大多地方婚俗中具有不可或缺性，基于彩礼返还引发的纠纷层出不穷。由于立法对彩礼返还规定过于简略，且各地习俗多样化，致使法院在处理彩礼返还纠纷时考量因素差异较大，影响到司法裁判的统一性。研究以福建省司法裁判为研究对象，分析彩礼返还纠纷司法裁判中存在的不足，建议应在确定彩礼性质范围的基础上参考民间习惯，厘清彩礼返还情形，结合彩礼习俗探究彩礼返还比例，统一“生活困难”认定标准，在法律与习惯融通下进一步完善彩礼的返还规则。

Betrothal gifts hold an indispensable role in the marriage customs of many regions, leading to frequent disputes over their return. Due to the overly simplistic legislative provisions on the return of betrothal gifts and the diverse customs across different regions, courts face significant variability in the factors they consider when handling such disputes, affecting the consistency of judicial decisions. This study focuses on judicial decisions in Fujian Province, analyzing the shortcomings in the adjudication of betrothal gift return disputes. It suggests that, based on defining the nature and scope of betrothal gifts, courts should reference local customs to clarify the circumstances under which betrothal gifts should be returned. Additionally, the study explores the proportion of betrothal gift returns in conjunction with local customs and proposes a unified standard for determining "financial hardship". These measures aim to further improve the rules for the return of betrothal gifts through the integration of law and custom.
