Istanbul, Turkey – A high-profile divorce case is unfolding in Istanbul, alleging infidelity and sparking a demand for a substantial financial settlement. Beyhan T. Has filed for divorce from Aydın Erdem, the chairman of Konda Research and Consultancy, and is seeking 50 million Turkish Lira (approximately $1.6 million USD as of February 24, 2026) in damages, citing a relationship between her husband and actress Dolunay Soysert. The case highlights the complexities of divorce proceedings involving prominent figures and raises questions about marital fidelity and financial responsibility within Turkish law.
The legal proceedings, initiated at the Istanbul 4th Family Court, center around accusations that Aydın Erdem engaged in an extramarital affair with Soysert. According to the petition filed by Beyhan T.’s lawyer, Ahmet Cidecioğlu, the couple married in 2006 and have two children. The filing alleges a pattern of infidelity throughout the marriage, culminating in a relationship with Soysert. This case is drawing significant media attention in Turkey, fueled by the public profiles of those involved and the magnitude of the financial claim.
The allegations detailed in the court documents paint a picture of a deteriorating marriage and alleged financial mismanagement. Beyhan T. Claims that Erdem has been living with Dolunay Soysert at a residence in Arnavutköy, Istanbul. The petition alleges that Erdem prioritized spending marital funds on lavish trips and expenses with Soysert, neglecting the financial needs of his family. This alleged behavior forms the basis for the claim of significant emotional and financial distress suffered by Beyhan T.
Details of the Allegations
The court filing outlines specific instances of alleged misconduct. It is claimed that Aydın Erdem informed his family of planned travel between August 4th and 13th, but then shared a photograph from the South of France, seemingly enjoying a vacation with Soysert while allegedly neglecting family obligations. The petition states that when requests were made for financial support for the family and their children, Erdem reportedly responded with a dismissive message, stating he was on vacation and the issues should be resolved independently. Türkiye Gazetesi reported on these claims, detailing the alleged message and the subsequent accusations of financial neglect.
The petition further alleges that Erdem and Soysert traveled together extensively, both domestically and internationally, staying at the same hotels and engaging in activities inconsistent with a faithful marriage. Beyhan T. Is requesting the court grant her temporary possession of the family home in Beşiktaş, Istanbul, during the divorce proceedings, and seeks full custody of their children. The 50 million TL in damages is being sought as compensation for the emotional trauma and financial hardship allegedly caused by Erdem’s actions. Sondakika.com initially reported on the filing of the lawsuit and the substantial damages requested.
Legal Arguments and Claims
The core legal argument centers on the violation of marital fidelity and the resulting emotional and financial harm. Turkish law recognizes the right to seek damages in cases of adultery, and the amount awarded is often determined by the severity of the emotional distress caused and the financial impact on the aggrieved party. The petition asserts that Aydın Erdem’s actions constitute a serious breach of his marital obligations, justifying the significant financial claim. The legal team representing Beyhan T. Is reportedly prepared to present evidence, including potential HTS (call detail records) data, to corroborate the claims of Erdem and Soysert’s close proximity and alleged relationship. Memleket.com.tr details the intention to use HTS records as evidence in the case.
The filing similarly highlights the alleged financial burden placed on Beyhan T. Throughout the marriage, claiming that Erdem consistently relied on her to cover household expenses and the costs of raising their children. This alleged financial imbalance further strengthens the claim for substantial damages, as Beyhan T. Seeks to be compensated for years of financial responsibility and the emotional distress caused by her husband’s alleged infidelity and financial mismanagement.
The Role of Dolunay Soysert
While Dolunay Soysert is not directly named as a defendant in the divorce proceedings, her alleged involvement is central to the case. The petition explicitly accuses Aydın Erdem of maintaining a relationship with Soysert, and the evidence presented will likely focus on establishing the nature and extent of their alleged connection. Soysert has not yet publicly commented on the allegations. The outcome of the case could potentially have implications for Soysert’s public image and career, depending on the evidence presented and the court’s findings.
Background on the Individuals Involved
Aydın Erdem is the chairman of Konda Research and Consultancy, a prominent polling and research firm in Turkey. Konda has played a significant role in shaping public opinion and providing data analysis for various political and social issues. Erdem’s position as a leading figure in the Turkish research landscape adds another layer of public interest to the case. Beyhan T. Is identified as the wife and mother seeking legal recourse following the alleged infidelity. Dolunay Soysert is a well-known actress in Turkey, with a career spanning television and film.
The case is currently in its early stages, and the court has yet to issue a ruling on the divorce petition or the request for damages. The next scheduled step in the legal process is expected to be a hearing where evidence will be presented and arguments will be made by both sides. The Istanbul 4th Family Court will ultimately determine the validity of the allegations and the appropriate resolution to the case. The proceedings are expected to be closely followed by the Turkish media and public, given the high-profile nature of the individuals involved and the significant financial implications.
As of February 24, 2026, no official statement has been released by either Aydın Erdem or Dolunay Soysert regarding the allegations. The legal proceedings are ongoing, and the outcome remains uncertain. The court’s decision will likely set a precedent for similar cases involving infidelity and financial claims in Turkish divorce law.
