Eva Jehrin

I have more than 25 years’ experience of dispute resolution. I represent clients both in arbitration and before courts of law and have acted as lead counsel in several landmark cases tried in the Swedish Supreme Court. I have a special focus on insurance and reinsurance law advising clients on coverage disputes and other insurance related disputes as well as on advisory and regulatory aspects of insurance law.

I also handle disputes in other financial sectors and in the infrastructure and construction area.

I became a partner at Westerberg in July 2021, from Baker & McKenzie where I was a partner for more than 20 years and headed the European insurance law practice. I am a member of the Swedish Bar Association since 1996 and graduated from Stockholm University (LL.M.) in 1989. I am a member of Association Internationale de Droit D’Assurances and the Swedish Insurance Law Association. I serve as a member of the board of the Swedish Sports Confederation since 2013.

Besides Swedish I am fluent in English.

Work highlights include acting for:

more than 40 reinsurance companies against the bankruptcy estate of a Swedish credit & guarantee insurer in arbitration and litigation arising out of coverage issues relating to reinsurance of financial guarantees.

  • a Finnish reinsurer against a Swedish insurer a<nd a Luxembourg bank in litigation relating to financial guarantees for real estate acquisition.
  • a German construction company against a Ukrainian State Entity in arbitration relating to a construction project at a damaged nuclear power plant.
  • a Norwegian insurer in a dispute over the quality of a portfolio of insurance policies purchased by the Norwegian company.
  • a Finnish insurer in litigation relating to co-insurance of elevator accidents in the US.
  • a UK life insurer in litigation relating to recovery of overpayments to pension insurance beneficiaries.
  • a Swedish insurer in litigation and arbitration arising out of business interruption claims in the mining and automotive industries.
  • a major supplier to the automotive industry in arbitration arising out of the insolvency of a Swedish automotive company.
  • a major Russian oil company in arbitration concerning a joint venture.
  • a US based insurer in litigation concerning coverage issues in D&O and Professional Indemnity claims.

Former positions include:

After a tenure of four years in the Swedish courts, including service in the Court of Appeal, I entered private practice in 1993. From 1998 until 2021 I was a partner with Baker McKenzie where I headed the dispute resolution and insurance law practice in Stockholm. I served as chairman of Baker McKenzie’s Insurance Practice Group during several years and was also appointed to several government committees in legislative matters.
